Brevo is an all-in-one marketing platform (formerly Sendinblue) — email, SMS, WhatsApp, chat, and a CRM — priced by email volume with unlimited contacts on paid plans.
Brevo is a marketer’s suite with an API attached. MailBlastr leads with the API: typed SDKs in 8 languages, a CLI, copy-paste quickstarts, signed webhooks, idempotency keys, batch endpoints, and an MCP server — while still shipping the campaign, segment, and automation UI marketers need.
On Brevo, unlimited automation and A/B testing arrive with the Business plan ($18+/month); Starter excludes them. Every MailBlastr plan — Free included — has visual automations, A/B testing, segments, topics, and polls.
Brevo’s transactional sending exists but plays second fiddle to the marketing suite. MailBlastr treats product email — delivery speed, event webhooks, searchable 30-day logs, suppression management — as the core product, with marketing built on the same rails.
Brevo’s free tier caps at 300/day and paid tiers meter by monthly volume with feature gates per tier. MailBlastr paid plans have no daily cap and one consistent feature set — tiers change volume, not capability.
If you want one login for email, SMS, WhatsApp, live chat, and a CRM — and your list is huge while your send volume is small — Brevo’s unlimited-contacts, pay-per-email model and channel breadth are a genuinely good fit for marketing-led teams.
The free tier (3,000 emails/month) needs no card — you can run the whole migration before paying anything.
Add your sending domain and follow the guided DKIM, SPF, and DMARC setup. One-click flows exist for Cloudflare, GoDaddy, and Namecheap; verification usually completes in minutes.
Replace your current send with one HTTPS request or a typed SDK in 8 languages. Batch endpoints, idempotency keys, and scheduling are built in.
Subscribe a webhook to delivered, opened, clicked, bounced, complained, and unsubscribed events — every request is signed so you can verify the source.
Bring audiences over via CSV or the contacts API; templates port as plain HTML or rebuild in the block editor.

For huge lists with tiny send volume, yes, and that is Brevo’s sweet spot. MailBlastr plans include contacts up to 250,000 on stock tiers, and its pricing rewards the opposite shape: high sending volume with a focused list, where Brevo’s per-email tiers climb quickly.
MailBlastr — the API is the product: 8 typed SDKs, CLI, signed webhooks, batch sends, idempotency, natural-language scheduling, and docs written for engineers. Brevo’s API covers the suite but the platform is designed around the marketing UI.
Starter excludes unlimited automation and A/B testing — those arrive with Business ($18+/month). MailBlastr includes automations (10,000 runs/month) and A/B testing on every plan, including Free.
No — MailBlastr is deliberately email-only. If multichannel campaigns are core to your strategy, Brevo’s breadth wins; if email is the job, a focused platform does it better.
Export contacts to CSV (or sync via API), port templates as HTML, verify your domain, and swap transactional calls to POST /emails or an SDK. Automation journeys rebuild quickly in the visual builder.
Free tier with 3,000 emails a month — API, campaigns, automations, and webhooks included. No card required.
