Loops vs Mailjet

A source-aware comparison of pricing, documented capabilities and workflow fit.

Short answer

These lines are generated from the pricing we track, not from a paid placement. How we score tools.

What Loops is

Loops is email for software companies: transactional and marketing sends in one place with a modern API. Keeping product and marketing email in one place with a modern API suits software teams who do not want two systems and two reputations. It is young, so campaign tooling is thinner than the established marketing platforms.

What Mailjet is

Mailjet handles transactional and marketing email with a collaborative template editor and European data hosting. European hosting and a template editor several people can work in at once make it unusual among developer-first senders. Raw scale features are a step behind the largest providers. The trade is scale, not usability.
