Email software for B2B, matched to how your deals close.

ActiveCampaign suits B2B teams that want one place for nurture sequences, scoring-style segmentation and sales handoffs. Standard CRM and ecommerce integrations are included from the Starter plan, so the first version of a sync between email and your CRM does not require an upgrade. Segmentation deepens on the next tiers: Plus adds standard segmentation and landing pages, Pro adds advanced segmentation, and Enterprise adds premium segmentation and a dedicated account team.

For a committee sale, the useful pattern is one track per role inside the same account. Champions receive proof and case material, economic buyers receive a business-case summary, and blockers receive security or compliance answers. The segmentation tiers decide how precisely you can split those groups, so plan the role model before you choose the plan.

Where it falls short: the price rises with the number of contacts, so a large lead database gets expensive faster than the cost per sales meeting suggests. Setting it up well takes weeks, not an afternoon, and a poorly built automation can send a series of identical messages to every person at a company. It is more tool than a small team with a short list needs.

Close is a CRM, and its email features sit inside the pipeline. Essentials includes email, built-in forms, calling and SMS, and a centralized inbox. Growth adds automated workflows, a power dialer and bulk email. For a sales team that already logs every call and reply in the CRM, this removes the sync problem entirely, because the sequences and the deal record are the same object.

The trade-off is that nurture for people who are not yet in a deal is a secondary job here. If you plan to run a long newsletter-style program to thousands of contacts who have no open opportunity, a dedicated email platform is usually the better base, with Close handling the deals.

Where it falls short: the price is per user, so the cost grows with headcount rather than with list size, and that is the opposite of most email tools. Calling and SMS usage are passed through at cost, which makes budgets less predictable for high-volume outbound teams.

Customer.io sends messages when something happens in your product or data: a user invites a colleague, an account reaches a usage threshold, a trial ends with no activity. For B2B teams with clean event data, that is a strong basis for account-aware journeys across email and other channels. The Essentials plan includes a visual workflow builder and basic data integrations, and profile-based pricing lets you model cost against the people you actually message.

It is the right choice when the messages depend on behavior. If your nurture is mostly content on a schedule, the event model adds work without adding much value. Ask whether your team can name the five events that should trigger a message before you buy it.

Where it falls short: someone has to own the event tracking, and poor event data produces poor journeys. Costs rise with profile count, and the Premium plan is priced by custom profile volume, so large programs need a sales conversation.

Brevo is the strongest budget option in this guide for a B2B team with a modest, predictable send volume. The free plan allows up to 300 emails a day with storage for up to 100,000 contacts, which covers a long period of nurture for a small team. Paid plans are priced by monthly email volume rather than contact count, so a large list of people who rarely open does not raise the bill in the same way.

Standard adds automation, A/B testing and advanced reports, which covers most lean nurture programs. Keep the daily cap in mind when you plan a launch: a single campaign to a large list can exceed what the free plan will send in one day.

Where it falls short: account-level logic is basic, and the CRM connection is simpler than in the sales-focused tools. A B2B team with complex buying committees will hit the limits quickly.

Mailchimp is a sensible choice for a small B2B company that sends an occasional update to customers, partners and prospects, and whose staff already know the interface. Its free plan is a usable place to start a list, and the contact-band pricing is easy to read.

Where it falls short: its pricing scales with contacts, and the cost rises steadily as the list grows. The depth of account logic and sales-side visibility is limited, so a team that outgrows simple sequences will need to move. If you do move, export tags and segments first and rebuild the most important ones by hand rather than trusting an import.

Specialist B2B firms, such as accountants, engineers or advisory practices, often win work through regular, expert writing. Kit's free plan includes landing pages, forms, unlimited broadcasts and audience tagging for up to 10,000 subscribers, so a practice can build a readership before paying anything. Visual Automations and sequences start on the Creator plan.

Where it falls short: Kit is built around individual subscribers, not company accounts, so you cannot model a buying committee in it. Sales visibility is limited, and it suits a relationship-led firm more than a sales team running a pipeline.

Drip is built around workflows: a trigger, a branch on behavior, and a series of messages. Its entry plan includes unlimited email sends, dynamic segments, onsite campaigns and up to 50 workflows. For a B2B team whose work is mostly reorders, onboarding of new accounts, or follow-up after a demo, this structure fits well, and each workflow can be read as a plain sequence.

Where it falls short: pricing is per person, and the plans run in steps, so a list just over a band boundary costs more than the list before it. It has no committee or account view, so role-based nurture must be built with tags and segments on individual people.

Moosend gives a small team automation and unlimited emails on a contact-based plan, with email credit packs for larger sends. For a B2B company that wants real nurture flows without a higher-tier price, it is a reasonable choice, and the annual billing option lowers the monthly cost noticeably.

Where it falls short: there is no ongoing free plan, the interface is less polished than the leaders, and its integrations are thinner. Check the integrations you need against its documentation before you sign up for the trial.

Klaviyo is a capable tool for online stores, where profiles are shoppers and the data comes from purchases and browsing. Its profile-based model does not map to company accounts, and B2B teams would have to fake that structure with tags. Unless your B2B business sells products through a store, look at the tools above first.
