Consulting edition · Updated October 7, 2026

Email software for consultants, chosen by how engagements are won.

For most consultants, ActiveCampaign is the best starting point, because its Starter plan at $15 a month for 1,000 contacts bundles marketing automation with standard CRM integrations. Prospect follow-up, client delivery notes and past-client check-ins can then run from the same contact record. If you mainly publish a newsletter, Kit\'s free plan covers up to 10,000 subscribers.

Who this guide is for

This guide is for independent consultants, advisers and fractional executives who sell engagements, retainers and workshops to a small number of clients. Your email has a different job from a store\'s. A prospect may read your newsletter for six months before they ask for a call. A proposal may need three follow-ups before it is signed or declined. A past client may refer you once a year, if you remind them at the right moment. Your list is smaller than a retailer\'s, but each contact is worth more.

That changes what matters in a tool. Pricing by contact count is more predictable than pricing by sends for a list of a few thousand people. Segmentation matters more than template volume, because you need to keep prospects, active clients and past clients apart. A free plan is useful early on, but only if it still lets you run the one or two automations that move deals forward. The sections below test each tool against those needs using only what each vendor publishes.

The prices here come from each vendor\'s pricing page as it stood on October 7, 2026. Plans change, and contact-based prices depend on the band you select, so confirm the figure on the pricing page before you commit.

The short comparison

Each row lists the plan that matters most for a consulting practice, its published price and the limitation you are most likely to notice. Where a vendor prices by contact band, the band the price applies to is named.

What it costs at three list sizes

Most consulting lists sit between a few hundred and ten thousand contacts. The table below shows the published price for the tools that list a figure at 1,000, 5,000 and 10,000 contacts. Where a vendor does not publish a price for that size, the cell says "pricing on request", which means you should use the vendor\'s contact selector to get the exact figure.

Tool and plan1,000 contacts5,000 contacts10,000 contacts
ActiveCampaign, Starter / Plus / Pro$15 / $49 / $79 per monthPricing on requestPricing on request
Kit, Free / Creator$0 / $33 per month, billed annually$0 (free plan)$0 (free plan, at the 10,000 limit)
Drip, people band$39 per month (1 to 2,500 people)$89 per month (4,501 to 5,000 people)$154 per month (9,001 to 10,000 people)
Mailchimp, contact tierPricing on request$100 per month (2,501 to 5,000 contacts)$135 per month (5,001 to 10,000 contacts)
Moosend, Pro$16 per month monthly, or $13 annually$48 per month monthly, or $38 annually$88 per month monthly, or $70 annually

Two things stand out. First, Moosend has the lowest published monthly figure at each of these sizes. Second, Kit is free at all three sizes, but its automations and sequences start on the Creator plan. A consultant who needs proposal follow-up at 5,000 contacts is therefore paying $33 a month at least, billed annually, which is not free in practice. Work out which feature you need before you read the free price as the total cost.

MailerLite\'s published tiers begin at 500 subscribers, with Comfort at $12 a month billed monthly and Power at $25 a month billed monthly. Campaign Monitor\'s published figures are for the 500-contact band. Those two are good value at small sizes, but you will need the pricing page selector for larger lists.

Tool by tool

Best for pipeline-driven consultancies

ActiveCampaign

What it does well for consultants. The Starter plan includes email marketing, marketing automation and standard CRM and ecommerce integrations. That combination is the reason it is the first pick here: a consultant can send a proposal follow-up, tag the contact and move the same person into a client path when they sign, without moving between tools. Plus adds standard segmentation and landing pages, and Pro adds advanced segmentation, which matters once you separate active clients by engagement level.

Where it falls short. The price rises with contact count, and the step from Starter to Plus is $34 a month at 1,000 contacts. A solo adviser with a list of a few hundred people may find the automation depth more than they need. Setting up CRM sync and tags takes an afternoon, and you should check that your CRM is supported before you commit.

Price. Starter $15 a month, Plus $49, Pro $79 and Enterprise $145, each at 1,000 contacts. A free trial is offered, but there is no free plan. See ActiveCampaign\'s pricing page.

Best for newsletter-led advisers

Kit

What it does well for consultants. The free plan covers up to 10,000 subscribers and includes landing pages, forms, unlimited email broadcasts, tagging and segmentation. An adviser who publishes a monthly framework or case teardown can build an audience at no cost while the practice is young. Subscriber tags then let you separate prospects from clients as the list grows.

Where it falls short. Visual automations and email sequences start on the Creator plan, and proposal follow-up depends on sequences. A consultant who wants that behaviour from day one pays for it. Kit\'s strength is publishing, not pipeline management, so if your revenue depends on deal stages you will probably want a CRM alongside it.

Price. Free up to 10,000 subscribers. Creator is $33 a month billed annually and Pro is $66 a month billed annually, with a 14-day free trial on paid plans and no credit card required. Pro adds subscriber signals, unlimited users and deliverability reporting. See Kit\'s pricing page.

Best for solos starting a list

MailerLite

What it does well for consultants. The free plan covers up to 250 subscribers and 2,500 monthly emails, which is enough for an adviser sending a monthly letter to a first group of contacts. The editor is simple, and it suits a practice that needs a regular habit before it needs deal logic.

Where it falls short. The free plan stops at 250 subscribers, and a consultant who speaks at events can pass that quickly. Paid plans begin at 500 subscribers, so the step up is larger than the step from an introductory list. Deal-stage follow-up is limited, so most consultants will eventually pair it with a CRM.

Price. Free up to 250 subscribers and 2,500 emails a month. Comfort is $12 a month billed monthly, or $10.80 billed annually, at the 500-subscriber starting tier, and its monthly email allowance is ten times the subscriber ceiling. Power is $25 a month billed monthly, or $22.50 billed annually, with unlimited monthly emails. See MailerLite\'s pricing page.

Best for a familiar editor on a small list

Mailchimp

What it does well for consultants. The free plan covers one audience, up to 250 contacts and 500 sends a month. That is enough to test whether a regular letter gets replies before you spend money. The Standard tier starts at $20 a month for the 500-contact selector and includes up to 6,000 emails a month at that size.

Where it falls short. Pricing follows contact tiers, so a practice that grows its network pays more each time it crosses a band. The free plan allows 250 sends a day, which can slow a larger first mailing. For proposal-driven selling, you will need to build the follow-up logic yourself, or add a second tool.

Price. Free up to 250 contacts. Essentials at 500 contacts is $13 a month billed monthly. Standard at 500 contacts is $20 a month, with the 2,501 to 5,000 contact band at $100 a month and the 5,001 to 10,000 band at $135 a month. A 14-day Standard trial is offered. See Mailchimp\'s pricing page.

Best for assessment funnels

Drip

What it does well for consultants. Drip is built around workflows and dynamic segments, and it includes onsite campaigns and up to 50 workflows on its listed plans. A consultant running a short diagnostic, such as a readiness assessment that leads to a discovery call, can map each answer to a different path. Unlimited email sends are included in the people bands.

Where it falls short. There is no ongoing free plan, and the price moves up in bands as the audience grows. Its workflow model suits funnels more than long newsletters, so a practice that mainly publishes essays may find it heavier than it needs.

Price. $39 a month for the 1 to 2,500 people band, $89 for 4,501 to 5,000 people and $154 for 9,001 to 10,000 people. The published figures are billed monthly, and there is a 14-day trial with no credit card required. See Drip\'s pricing page.

Best low-cost automation

Moosend

What it does well for consultants. Moosend has the lowest published monthly price among the tools covered here at the sizes that matter most. Its Pro plan is contact-based and includes unlimited emails for the listed contact count. A lean practice that wants a few automated sequences, such as a welcome path for new subscribers and a follow-up after a proposal, can run them without paying for a larger suite.

Where it falls short. Email credit packs are sold separately, starting at $350 a month for 350,000 credits, so heavy sending increases the bill. The design options are plainer than those of the larger brands, and you should test the integrations you need, especially your CRM, before you rely on them.

Price. At 500 contacts, Pro is $9 a month billed monthly or $7 billed annually. At 1,000 contacts it is $16 monthly or $13 annually, at 5,000 it is $48 monthly or $38 annually, and at 10,000 it is $88 monthly or $70 annually. There is a 30-day trial with no credit card. See Moosend\'s pricing page.

Best for volume and a free daily allowance

Brevo

What it does well for consultants. The free plan allows 300 sends a day for up to 100,000 contacts, which can serve a large network with light mailings. Starter is $9 a month for 5,000 emails a month with no daily sending limit, and Standard is $18 a month and adds automation, A/B testing and advanced reports.

Where it falls short. Paid plans are priced by monthly email volume, so a consultant who mails a large network several times a month pays for each send. Automation and reporting sit above the entry tier, which means the free plan is best for occasional mailings rather than proposal sequences.

Price. Free with 300 sends a day. Starter at $9 a month from 5,000 emails a month, and Standard at $18 a month. Plans can be billed monthly or yearly, and the yearly toggle on the pricing page shows the discounted figure. See Brevo\'s pricing page.

Best for event-led advisers

GetResponse

What it does well for consultants. GetResponse includes landing pages, signup forms, welcome series and one automation workflow on its Starter plan. Its higher tiers add unlimited workflows, advanced audience segmentation and webinar tools. An adviser who runs roundtables or webinar briefings can pair the sign-up page with the follow-up sequence in one platform.

Where it falls short. There is no ongoing free plan, only a free trial. Webinars are on the Creator plan, which sits at the top of the range, so the cost rises fast if you need them. Abandoned-cart recovery on the Marketer tier is aimed at online stores, and you will not need it.

Price. Starter is $19 a month billed monthly or $15.58 billed annually. Marketer is $59 monthly or $48.38 annually, and Creator is $69 monthly or $56.58 annually. See GetResponse\'s pricing page.

Best for polished templates

Campaign Monitor

What it does well for consultants. Campaign Monitor is focused on email design. For a consultant whose newsletter is effectively a printed briefing with a strong visual identity, that focus is useful. The Premier plan adds phone support, which some practices want when they cannot afford a sent email to go wrong.

Where it falls short. Automation depth is not the emphasis, so proposal sequences and deal-stage logic need extra work. There is no ongoing free plan, and the trial is limited to 500 contacts and 500 emails.

Price. Lite is $13 a month billed monthly or $11.70 billed annually at the 500-contact band. Essentials is $31 monthly or $27.90 annually for unlimited email sends, and Premier is $171 monthly or $153.90 annually. See Campaign Monitor\'s pricing page.

Best for simple briefing invitations

Constant Contact

What it does well for consultants. Constant Contact is straightforward to use for invitations to a briefing, a roundtable or a seasonal update to an established list. The Standard plan adds automation, scheduling and A/B testing, and Premium adds advanced automation, segmentation, reporting and 500 SMS a month.

Where it falls short. There is no free plan, and the trial is the only way to try it before paying. Contact count sets the exact price, so you need the selector to know the cost. Its strengths are event-style sends rather than deal-stage sequences.

Price. Lite is $12 a month billed monthly or $10.20 billed annually. Standard is $35 monthly or $29.75 annually, and Premium is $80 monthly or $68 annually. A free trial is offered with no credit card required. See Constant Contact\'s pricing page.

How to choose in four questions

1. Where does the revenue come from? If most of your work starts with a proposal, you need follow-up logic that can wait for a reply and then branch on the answer. Look for automation and CRM connections first. If most of your work comes from referrals and renewals, you need a clean past-client list and a calendar of check-ins. A simple tool with good tagging is usually enough.

2. How big is the list you will have in a year? Choose the plan for the band you will reach in twelve months, not the one you have today, but do not pay for a band you will not reach. Use the contact selector on each pricing page. Moving up a band mid-year is usually a small change if the tool handles imports cleanly.

3. Do you need automations on day one? Some tools keep sequences behind paid tiers. Kit\'s free plan, for example, does not include visual automations or sequences. If you need them immediately, compare the cost of the first paid tier, not the free plan.

4. Who will maintain it? A consultant with no time for administration needs a tool that stays simple. Choose the smallest set of automations that supports your three main jobs: proposal follow-up, past-client check-ins and referral requests. Add more only when a specific job is not being done.

Setup checklist for a consulting list

Setting up a consulting list is mostly about segmentation and timing, not design. The checklist below covers the steps most practices skip, with a check to run before moving on.

StepWhat to doCheck before you move on
1. Clean the listExport contacts and remove duplicates and anyone who has asked not to hear from youEvery record has a source tag showing how the person joined
2. Separate the groupsCreate prospects, active clients and past clients as distinct segmentsNo contact sits in two primary groups at once
3. Build proposal follow-upTag the contact when a proposal is sent and start a short sequence with reminders at day 7 and day 21The sequence stops automatically when the proposal is accepted or declined
4. Set past-client check-insSchedule a quarterly note with a useful update and an optional call invitationEach message has a working unsubscribe link and matches the client\'s consent
5. Add a sign-up pageCreate one landing page for a diagnostic or briefing, with one form field beyond name and emailThe sign-up tag appears on the new contact in your tool
6. Connect your CRMLink the tool to the CRM you use for dealsA test contact moves between stages without duplicates
7. Check deliverySend a test to addresses at several email providers you useThe message arrives in the inbox, not in spam, and renders correctly on a phone

Workflows that suit a consulting practice

Three workflows cover most consulting email. Build them in this order, because each one generates data for the next.

The authority list. Send one monthly letter with a framework, a client example and one clear next step. Keep the letter short enough to read between meetings. The aim is to be remembered by people who are not yet ready to buy, so the letter should never read as a sales pitch. Track which topics get replies, and use those replies to decide what to write next.

The proposal follow-up. A proposal that goes unanswered is more often a timing problem than a rejection. A sequence that offers a call, answers a likely objection and asks whether the scope needs changing gives the prospect a reason to reply. Keep the number of messages small, and stop the sequence as soon as the prospect responds, because a sequence that continues after a reply reads as careless.

The past-client check-in. Clients who have finished an engagement are your best source of referrals, but they rarely think of you unprompted. A quarterly note that shares something useful, such as a benchmark or a short case, keeps the relationship warm. Ask for a referral only after a clear result, when the client is most likely to be pleased with your work.

Keep the three groups apart. A prospect who receives a client update may be confused, and a client who receives a sales sequence may feel their trust has been misread. Segmentation is the single feature most worth checking before you choose a tool.

Frequently asked questions

Which email tool should a consultant start with?

For a practice that sells engagements through proposals and referrals, ActiveCampaign is the strongest starting point. The Starter plan is $15 a month at 1,000 contacts, and it includes marketing automation and standard CRM integrations, so prospect, client and past-client messages can run from one contact record. If you mainly publish a newsletter and have no need for proposal automation yet, Kit's free tier covers up to 10,000 subscribers.

Is there a free option that is usable for a consulting practice?

Yes, with limits. Kit's free plan covers up to 10,000 subscribers and includes landing pages, forms, unlimited email broadcasts and tagging. Visual automations and email sequences begin on the paid Creator plan, so proposal follow-up sequences need a paid tier there. MailerLite's free plan covers up to 250 subscribers and 2,500 emails a month, and Mailchimp's covers up to 250 contacts and 500 sends a month with a 250-per-day cap. Brevo's free plan allows 300 email sends a day for up to 100,000 contacts.

What will 5,000 contacts cost?

It depends on the tool. On Moosend's Pro plan the price at 5,000 contacts is $48 a month billed monthly, or $38 a month billed annually. Drip lists $89 a month for the 4,501 to 5,000 people band. Mailchimp lists $100 a month for the 2,501 to 5,000 contact band. ActiveCampaign's starting prices scale with contact count, so use its pricing page selector for the exact figure at that size. Kit is free up to 10,000 subscribers on its free plan.

Do I need a CRM to run proposal follow-up emails?

You need a reliable trigger. The simplest setup tags a contact when a proposal is sent, starts a follow-up sequence, and removes the tag when the proposal is accepted or declined. A CRM makes this easier to manage across many deals. ActiveCampaign's Starter plan includes standard CRM integrations, so check that your CRM is on the supported list before you choose a tool for that reason.

Can I email past clients about new services?

Usually you can contact people who have bought from you before, but the rules depend on your country and on what each person agreed to when they gave you their address. Keep a record of how each contact joined your list, offer an easy unsubscribe in every message, and keep past-client and prospect lists separate so each group receives only what it expects. If you are unsure, check the local rules or ask a qualified adviser.

When should a consultant move to a higher plan?

Move up when a specific feature is blocking your work, or when your list crosses the next pricing band. Examples include needing advanced segmentation to separate clients by engagement level (ActiveCampaign's Pro plan lists advanced segmentation), or needing visual automations on a list that has outgrown the free tier (Kit's Creator plan). Do not upgrade simply because a list is growing; check that the new plan changes something you actually do.

Why are some popular email tools missing from this guide?

This guide covers tools whose published plans fit a consulting practice: a small to mid-sized contact list, low-volume broadcasts, and automation for proposals and check-ins. Several tools are built mainly for online stores or product-event data, and their plans are priced around volumes and features a consulting practice rarely needs.
