Editorial verdict · Who it’s wrong for

Who shouldn’t buy Mailjet?

A direct read on the buyers Mailjet is the wrong fit for — sourced from the same editorial team that ranked the full Transactional Email Software category.

Worst for

North American greenfield dev projects (Postmark/Resend dominate) and dedicated email-marketing buyers (Brevo, Mailchimp wins).

For context: who it IS for

French, German, and other EU SMB/mid-market firms with strict EU data residency requirements and a desire for EUR-native billing.

Target size: 1–500 · EU SMB and mid-market with residency requirements

Why we say this

Editorial pulled these weaknesses from Mailjet’s product card in our Top 10 Transactional Email Software for 2026:

  • ! Brand recognition lower outside continental Europe
  • ! Under Sinch ownership, narrative has fragmented between Mailjet and sibling Mailgun
  • ! Dev mindshare has shifted to Postmark and Resend for greenfield projects
  • ! Marketing/campaigns side weaker than dedicated email-marketing vendors
  • ! Pricing has crept up under Sinch ownership

If Mailjet is wrong for you, consider these instead

Same Transactional Email Software category, different best-fit buyer.
