This is hands-down the worst email marketing tool I’ve ever encountered, and likely the worst deal on AppSumo in the field. I’ve used many platforms, but this one stands out for all the wrong reasons.

Major Issues:
1. Horrible Support: The customer service is unresponsive and unhelpful. Don’t expect assistance if you run into issues.
2. Outdated Subscription Forms: The design looks like it’s from the early 2000s, and the customization options are practically nonexistent.
3. Clunky Campaign Builder: The interface is painfully outdated. There’s no drag-and-drop functionality, which is standard in most modern platforms. Creating and sending a campaign is a nightmare—what takes mere minutes on Brevo will take hours here.
4. Privacy Concerns: The app lacks a proper “unsubscribe form.” The only way for subscribers to opt out is by clicking a link in an email or contacting you directly, forcing manual unsubscriptions. This is a blatant disregard for user privacy and makes the process unnecessarily difficult for both subscribers and the account owner.
5. Terrible Default Setup: The default login page isn’t even in English—completely unprofessional and laughable for an international deal.
6. Export Limitations: While it’s easy to import subscribers, exporting them is a frustrating ordeal. There’s no seamless way to transfer data to other providers in Excel or any common format.
7. Basic Features: The app lacks essential tools like modern stats tracking, integrations, and functional subscription or installation forms.

Overall Performance:

The indelivery rate is high. The outdated interface to the lack of integrations. Compared to professional platforms like Brevo or MailerLite, this app scores a zero.

Recommendation:

Avoid this app entirely. It’s no surprise they keep bringing it back to AppSumo as a “deal” every few months—it clearly can’t sustain itself otherwise. If you’re serious about email marketing, invest in a reliable platform like Brevo or MailerLite, which offer drag-and-drop builders, modern designs, better integration, and respect for subscribers’ privacy.

I regret purchasing this app and wish I could get a refund, but unfortunately, it’s too late. Don’t make the same mistake—steer clear of this deal. If you still have time to refund it, then you have made the correct decision!
