When Stripo may suit you better

Many people work on a few emails: unlimited users can cost less than per-user pricing.
You need AMP emails or countdown timers.
You want a large library of ready-made templates and modules.
You need simultaneous editing and element locking, which their plugin documents.

When Mailblocks is the better fit

Many users each edit their own emails: a price per active user is easier to predict.
You want designs to stay with you. Their v2 plugin keeps a reference copy of each email in Stripo’s database; Mailblocks hands the HTML and JSON to your page and keeps none.
You want an AI builder without supplying your own OpenAI key.
You want MJML and a design JSON you can store and reopen.
