Email software for HR teams, chosen by what people ops actually sends.
For most HR teams, Brevo is the best first pick. Its free plan covers up to 100,000 contacts with a limit of 300 sends a day, and its Starter plan costs $9 a month billed monthly for 5,000 emails. A 800-person company sending four company updates a month (3,200 emails) would pay $108 a year on that plan. Teams that run structured onboarding or alumni programs should add a journey tool such as ActiveCampaign or Kit alongside it.

HR email covers three jobs that rarely share one template. The first is broadcast: policy changes, benefits enrolment windows, holiday closures and all-hands recaps, sent to the whole company or to one location. The second is lifecycle: a new hire needs a pre-start checklist, a first-week schedule and a 30-day check-in, and each message depends on a start date held in the HR system. The third is the alumni and rehire list, which keeps growing for years after people leave and needs a clear consent trail.
Each job pushes tool choice in a different direction. Broadcast favors cheap, reliable sends and simple templates. Lifecycle needs date-based triggers and some branching by role or location. Alumni needs a low cost per contact, because the list rarely shrinks. Few tools do all three well at a price a 300-person company will accept, so most HR teams end up with one main tool and a second for the part it handles poorly.
Employee data is also more sensitive than customer data. A welcome email needs a first name, a work address, a start date and a manager's name. It does not need performance notes, health information or disciplinary records, and those should never be imported into a marketing tool. Ask each vendor for its data processing agreement before the first import. The pricing pages cited in this guide do not answer questions about data location or processing terms.

What it costs at three list sizes
HR lists are usually sized by headcount plus alumni, so the same company can land in very different price bands depending on how many former employees it keeps. The table below uses three realistic contact counts: 500 (a small firm), 2,500 (a mid-size company with some alumni) and 10,000 (a large employer with a long alumni list). Where a vendor's page does not publish a price for that band, the cell says so.
Two calculations show how this plays out. A 500-person company sending four updates a month sends 2,000 emails, which fits within Brevo's free plan as long as no single send goes above 300 recipients in one day. A single all-staff notice to 500 people does not fit, so that company needs the Starter plan at $9 a month, or $108 a year. At Mailchimp's Standard rate of $20 a month, the same company would pay $240 a year, and at Comfort in MailerLite it would pay $144 a year at the 500-subscriber tier.

Company notices
Brevo
Free plan up to 100,000 contacts · Starter $9/mo billed monthly · Standard $18/mo
Brevo suits the broadcast side of HR best. A notice about a benefits deadline, a policy change or a holiday closure goes to the whole company from one account, and the list can hold every current employee and a long alumni list without a per-contact charge on the free plan. The Starter plan's 5,000 emails a month covers a company that sends a few updates each month. Standard adds automation, A/B testing and advanced reports from $18 a month.
The weak point is the daily cap. The free plan allows 300 sends in a day, so a single notice to 500 people will not go out on the free plan. A people team should plan to move to Starter the first month it sends to the whole company at once. For higher volume, the Professional plan starts at $499 a month for 150,000 emails, with up to 2 million contacts.
For journey logic, such as a 90-day onboarding sequence that branches by department, Brevo is thinner than ActiveCampaign. Most HR teams using Brevo pair it with a second tool for new-hire journeys.
Free up to 250 subscribers · Comfort $12/mo monthly · Power $25/mo
MailerLite is the cheapest way for a small HR team to start with a proper list and a real editor. The free plan covers 250 subscribers and 2,500 emails a month, which is enough for a 200-person company's internal newsletter. Once the list passes 250, the Comfort plan starts at $12 a month billed monthly, with a monthly email allowance of ten times the subscriber tier, so the 500-subscriber tier allows 5,000 emails a month.
Power, at $25 a month billed monthly or $22.50 billed annually, removes the monthly email cap. That matters for a company that sends a weekly digest to everyone. The limit is depth: MailerLite's automation is adequate for a welcome series and a few reminders but not for an onboarding program with branches by role.
Pick MailerLite when the team is small, the budget is tight and the main need is an honest internal newsletter. Move on when onboarding gets complicated.
Free up to 250 contacts and 500 sends a month · Standard $20/mo at 500 contacts
Many HR staff already know Mailchimp from marketing roles, so the learning curve is short. The free plan covers one audience of up to 250 contacts and 500 sends a month, with a limit of 250 sends a day. That is enough for a small company's team updates. The Standard plan starts at $20 a month for the 500-contact selector, with up to 6,000 emails at that size.
The cost curve is the issue for HR. Pricing follows the contact count, so a list that grows with alumni moves into higher bands quickly. The 2,501 to 5,000 contacts band is listed at $100 a month, and the 5,001 to 10,000 band at $135 a month. A company with a long alumni list should compare these figures to Brevo's free plan before committing.
Mailchimp is a sound choice for a small company that wants a familiar interface and a short setup. It is not built for onboarding programs that need detailed branching.
Lite $12/mo monthly ($10.20 annual) · Standard $35/mo · Free trial, no free plan
Constant Contact works well when the main HR job is event communication: invitations to an all-hands, a town hall, a wellbeing day or an awards evening. Its templates are simple, and a coordinator who has never used an email tool can send an invitation without training. The Lite plan starts at $12 a month billed monthly, with monthly sends up to ten times the contact count.
Automation is the limit. Scheduled follow-ups and A/B testing sit on the Standard plan at $35 a month billed monthly, or $29.75 billed annually. Premium, at $80 a month or $68 billed annually, adds advanced automation and segmentation. Pricing for each contact band is not shown on the pages reviewed here, so a 2,500-person company should ask for a quote.
There is no free plan, only a free trial that does not require a card. Use the trial to test the event flow before signing up.
Starter $15/mo at 1,000 contacts, billed monthly · Plus $49 · Pro $79 · Enterprise $145 · Free trial
ActiveCampaign is the tool in this guide built most directly around journeys. A new-hire sequence can branch by department, location or role, pause for a manager's confirmation and resume once a task is completed. The Starter plan includes email marketing, marketing automation and standard CRM and ecommerce integrations, so the journey logic is available from the entry tier.
The price starts at $15 a month for 1,000 contacts, billed monthly. Plus at $49 adds standard segmentation and landing pages, Pro at $79 adds advanced segmentation, and Enterprise at $145 adds premium segmentation and a dedicated account team. Those starting prices assume 1,000 contacts, and the price rises with the list. A company that wants onboarding journeys for staff but also keeps a large alumni list should model the cost before choosing it.
Use ActiveCampaign for onboarding and talent pipelines, and keep a cheaper tool for broadcasts. It has no free plan, so the trial is the only way to try it without paying.
Free up to 10,000 subscribers · Creator $33/mo billed annually · Pro $66/mo billed annually · 14-day trial on paid plans
Kit fits an HR team that wants to build a candidate audience before roles open. The free plan includes landing pages, forms, unlimited email broadcasts and audience tagging for up to 10,000 subscribers. Culture stories, engineering blog posts and interview-process notes can all go to a list of people who might apply later.
The limit is automation. Visual automations and email sequences start on the Creator plan at $33 a month billed annually. Pro at $66 a month billed annually adds subscriber signals, unlimited users and deliverability reporting. Kit does not cover staff notices and alumni programs well, because its strength is publishing and audience growth, not internal operations.
Use Kit for talent attraction, paired with a tool that handles staff communications.
GetResponse has a clear use case in HR: learning and development. The Creator plan includes webinars alongside email and funnels, which suits compliance refreshers, product training and enablement programs that run as live sessions. Marketer, at $59 a month or $48.38 billed annually, adds unlimited workflows and advanced audience segmentation.
The Starter plan at $19 a month allows one automation workflow, so it is too small for a training program with several tracks. Training sign-up and reminder flows are the typical reason to move up. GetResponse has no free plan, only a free trial.
If your HR job is mainly staff communication, GetResponse is more tool than you need. If it is mainly learning delivery, it is a sensible fit.
Lite $13/mo monthly ($11.70 annual) · Essentials $31/mo ($27.90 annual) · Premier $171/mo · 30-day trial
Campaign Monitor makes sense when a CEO or HR director's letters must look carefully designed. Its editor handles layout well across email clients, and the prices in the 500-contact band are published on the pricing page. Lite at $13 a month monthly caps sends at five per subscriber a month. Essentials at $31 a month allows unlimited sends.
Automation depth is the weakness. Campaign Monitor is built mainly for campaigns rather than journeys, so onboarding and alumni sequences need extra work or a second tool. Pricing above the 500-contact band is not shown on the pricing page, so larger employers should ask for a quote.
Choose it for leadership and company-wide communication, not for the full HR stack.
Several other tools are worth a look in narrower cases. Moosend's Pro plan is $9 a month billed monthly for 500 contacts, or $7 a month billed annually, and it includes automation for small teams on a 30-day trial. AWeber's Lite plan costs $15 a month for 500 subscribers and 5,000 sends, with a 14-day trial, and suits HR teams that want a simple broadcast tool with a long track record. Drip starts at $39 a month for up to 2,500 people, with unlimited sends and up to 50 workflows, and it fits a company with a strong culture-and-merchandise program that wants store-style flows.
Loops offers a free plan of up to 4,000 sends in a rolling 30 days, and its paid Growing Audience plan starts at $99 a month. It is built for product and engineering teams and is a poor fit for general HR work. Klaviyo and Customer.io are built for ecommerce and product messaging. Klaviyo's email plans start at $20 a month for 500 profiles, and Customer.io's Essentials plan starts at $100 a month. Neither is a sensible default for HR, though an engineering-led company might use Customer.io for in-product onboarding alongside an HR tool.
How to choose for your HR team
Start with the list size, not the feature list. Count current employees, the alumni you plan to keep emailing and any candidates in a talent pool. Then count how many emails you will send each month, including reminders and two-stage notices. Those two numbers set the price band on almost every plan in this guide.
Next, decide which of the three HR jobs carries the most weight. A team that mainly sends notices needs a tool with generous sending limits and a clean editor. A team that runs onboarding needs branching and date-based sequences. A team that manages alumni needs a low per-contact cost and a clear consent process. Pick the tool that does the largest job well and add a second tool only when the first one clearly fails at the others.

Setup and migration for people teams
Most HR email problems start at the import step. Export only the fields each message needs. A list used for company notices needs name, work email and location. A list used for onboarding also needs the start date. Everything else should stay in the HR system. Keep staff, alumni and candidates in separate lists or tagged segments from day one, because each group has different consent rules and different messages.
Authenticate your sending domain before the first company-wide send. Your IT team should set up SPF, DKIM and DMARC records so that staff notices land in inboxes rather than spam folders. Ask the vendor for its setup guide, which normally names the records needed. Send a test message to a small group in HR first, and check the links to the benefits portal and the policy pages, because a broken link in an all-staff notice is hard to recall.
Alumni lists need an opt-in when people leave. Record the date and wording of each consent, and keep a clear unsubscribe link in every message. Clean the list once a quarter by removing bounced addresses. This keeps costs down on contact-based plans and keeps sender reputation healthy.
Step
What to do
Why it matters for HR
1. Trim the export
Keep name, work email, location, department and start date only
Sensitive HR data stays out of marketing tools
2. Separate the groups
Create separate lists or tags for staff, alumni and candidates
Each group needs different messages and different consent
3. Authenticate the domain
IT sets up SPF, DKIM and DMARC before the first company send
Staff notices reach inboxes instead of spam folders
4. Record alumni consent
Ask for opt-in at exit and store the date and wording
You can show where each address came from
5. Key onboarding to start dates
Use a start-date field to trigger the 90-day sequence
Messages arrive at the right point in the new hire's first months
6. Check links first
Send a test to HR staff and open every link to benefits and policy pages
A broken link in an all-staff notice is hard to correct
7. Clean the list quarterly
Remove bounces and inactive alumni on a set schedule
Contact-based plans cost less and sender reputation stays healthy
Verdict
For most HR teams, start with Brevo. Its free plan covers up to 100,000 contacts, and Starter at $9 a month billed monthly covers 5,000 emails, which is enough for company notices and policy letters at a small or mid-size employer. Add ActiveCampaign when onboarding needs branching by role, starting at $15 a month at 1,000 contacts. Use MailerLite if the team is very small and the budget is tight, and Constant Contact or Campaign Monitor when event invitations or leadership letters are the main job.
Whatever you choose, keep staff, alumni and candidates on separate lists, export only the fields each message needs, and check the vendor's pricing page against your actual list size before you commit.
Which email tool should a small HR team start with?
MailerLite is the usual starting point. Its free plan covers up to 250 subscribers and 2,500 emails a month. When the list grows past that, the Comfort plan starts at $12 a month billed monthly at the 500-subscriber tier, or $10.80 a month billed annually.
Can HR send onboarding emails that start from each new hire's start date?
Yes, if the start date is stored as a field on each contact. ActiveCampaign is built for this kind of branching sequence, and its Starter plan includes marketing automation from $15 a month at 1,000 contacts, billed monthly. Cheaper plans can send a fixed series, but they usually cannot branch by role or location as cleanly.
Should staff and alumni live in the same list?
Keep them in separate lists or segments. Current staff receive operational notices; former employees need a clear opt-in and a way to leave, and their messages are different in tone and purpose. Most plans bill by contact, so a list that keeps growing with alumni raises the cost of every send.
Does email software replace text messages for interview logistics?
No. Text messaging is usually a separate product or add-on. The plans listed in this guide do not show SMS as included, so check the vendor's pricing page before assuming it is part of the plan you choose.
Is it safe to import the full employee list into a marketing tool?
Import only what each message needs: name, work email, location, department and start date. Keep health, disciplinary and compensation data out of marketing tools entirely. Ask each vendor for its data processing agreement before the first import, because a pricing page does not answer questions about data location or processing terms.
When should an HR team move to a more expensive plan?
Move up when your send volume passes the plan limit, or when onboarding needs branching logic that the cheaper tier does not include. For example, Brevo's Starter plan covers 5,000 emails a month, and Kit's automations start on the Creator plan at $33 a month billed annually. Upgrade based on the limit you actually hit, not on the feature list.
