We rate Mailjet 4/5. Combined transactional and marketing email, making it especially useful for developers and solopreneurs. The main tradeoff: free tier has daily sending limit.
About Mailjet
Mailjet combines transactional email (password resets, order confirmations) and marketing email (newsletters, campaigns) in one platform. This dual capability means solo founders don't need separate services for different email types.
The email API is developer-friendly with SDKs for every major language. Send transactional emails via SMTP or REST API with detailed analytics on opens, clicks, and bounces. Deliverability rates are competitive with dedicated transactional services.
The marketing side includes a drag-and-drop email builder with real-time collaboration — multiple people can edit the same email simultaneously, like Google Docs for email design.
The free tier includes 6,000 emails/month (200/day limit). Essential plan starts at $17/month for 15K emails with no daily limit. Premium ($27/month) adds advanced automation, A/B testing, and segmentation.
For solo founders, Mailjet's free tier is a great starting point — 6K emails/month covers most early-stage needs. Having transactional and marketing email in one place simplifies your stack and billing.
Limitations: the daily sending limit on the free tier is restrictive, advanced automation features are locked behind the Premium plan, and the template designs aren't as modern as competitors like Mailchimp.
