Choose Brevo if

  • You need SMS, CRM, and marketing automation in one vendor.
  • Non-technical marketing users own most email workflows.
  • You prefer a suite over a focused email API.

Choose SMTPfast if

  • You want an email API rather than a CRM that also sends email.
  • Your integration lives in code and you would rather configure it there than in a UI.
  • You need delivery debugging that goes deeper than sent or not sent.

Migration checklist

  1. 1Separate transactional API usage from CRM/marketing workflows.
  2. 2Create an SMTPfast account and generate an API key with email:send scope.
  3. 3Add and verify your sending domain with DKIM, SPF, DMARC, and MAIL FROM records.
  4. 4Send a low-volume test message and confirm events appear in the SMTPfast logs.
  5. 5Move production traffic gradually while watching bounces, complaints, and suppressions.
  6. 6Move transactional sends first; migrate broadcasts only if SMTPfast covers the required segmentation.

Frequently asked questions.

Is SMTPfast better than Brevo?

Brevo is stronger as a broad marketing/CRM/SMS suite. SMTPfast is stronger for focused developer email infrastructure with API/SMTP sending and delivery operations.

When should I still choose Brevo?

Choose Brevo when its core strength matches your team: Teams that want email marketing plus CRM/SMS features in one vendor. SMTPfast is a better fit when you want a developer-first SES-backed API with queues, webhooks, tracking, suppressions, and a focused dashboard already handled.

How hard is it to migrate from Brevo to SMTPfast?

Most migrations start with domain verification, a test API key, and one low-risk transactional email path. Resend-compatible payloads are especially quick to move; older providers may require mapping template, webhook, and suppression behavior.
