Marketing automation well beyond what we ship

Pricing and free tier

Unitpost: 5,000 emails/month, 200/day, no credit card; On paid plans your monthly price is a sending allowance you spend at your tier's rate, and it refreshes every month. Marketing and unlimited contacts are included rather than billed as add-ons.
Brevo: 300 emails/day (~9,000/month); Marketing plans by contact count plus separate transactional email credits, with higher tiers gating channels like WhatsApp.

How do I migrate from Brevo?

Paste a read-only Brevo API key into the Migration Assistant and it previews everything that would carry over — contacts, segments, topics, templates, domains, suppressions, and webhooks. Nothing is written until you accept, and Brevo keeps sending the whole time, so there is no downtime. It takes about four minutes.

Two things do not carry over: sending domains must re-verify with freshly generated DKIM keys, and webhook signing secrets are regenerated. Dynamic segments import as a static snapshot of their members.

Frequently asked questions

Brevo's free tier is bigger — why pick Unitpost?

It is bigger, at roughly 9,000 emails a month against our 3,000, and if raw free volume is the deciding factor you should take theirs. The reason to pick us is what the product is for: Brevo is a marketing suite that also has an API, and Unitpost is email infrastructure that a developer drives. If your primary interface is code, that difference shows up daily.

Does Unitpost support SMS or WhatsApp?

SMS, yes. It is included on every paid plan, with the same contacts, API key, and webhooks as email. Texts draw on the same monthly sending allowance as email, at a published per-country rate, so there is one balance rather than a separate SMS credit pack. SMS is not on the free plan. WhatsApp is not shipped yet. If you need WhatsApp or chat today, Brevo has them and we do not.

Can I replace Brevo entirely with Unitpost?

Only if you are using it for email and SMS. We cover transactional and marketing email, SMS on paid plans, contacts, segments, topic-based unsubscribes, and campaigns. We do not have a CRM, landing pages, live chat, or WhatsApp. Teams using Brevo as their whole marketing stack should expect to keep parts of it.
