Honest first impression: I haven't run heavy campaigns yet, but I've explored the platform and it has everything I need in one place, newsletter editor, automations and transactional SMTP.
The automations look simple and intuitive, and they'll hopefully replace what I'm currently doing with external tools like ActivePieces. The embedded subscription forms work well out of the box, and having SMTP, campaigns, landings and surveys under one dashboard is a win. Also a plus: Spanish company, EU servers and support in Spanish.
The not-so-good:
The official WordPress plugin feels very basic and isn't up to date, it's only tested up to WP 6.8.5 and I couldn't get it to work on my WordPress 6.9.4 install. Luckily the embedded forms cover my needs for now, but a properly maintained WP plugin would be a big plus. Also, compared to other AppSumo deals, the monthly email cap isn't as generous as some alternatives, especially for transactional email, but I guess you can always pair it with another tool (like I did).
Overall a solid tool that I'll keep exploring. Will update the review once I have real campaign data.
4 tacos for now, mostly because of the outdated WordPress plugin and because I haven't tested everything in depth yet. Honestly it deserves a solid 4.5 from me, but since half points aren't an option I'm going with 4. Once they update the WP plugin and I dig deeper into the app, I'll happily bump it to 5.
