If you’re a Zoho One user, ZeptoMail is a no brainer. If you’re not, at 2.50 € per 10,000 emails it’s a very affordable alternative to other vendors on the market.

We started using Zoho ZeptoMail back when it was still called TransMail. It’s a useful addition to the Zoho One universe and a great tool if you have a custom developed application that sends out emails. We also use it for WordPress as deliverability is better than with SMTP or phpmailer.

There is not much to dislike, it does well what it is supposed to do. The mobile version of ZeptoMail is not that great, so that’s a small minus. I mostly use it on my desktop, so not a big deal.

I know it's a decent solution, but it takes a long time to implement and get the service up and running. Apart from technical limitations and bureaucracy, it is a functional service.

Apart from the fact that it is yet another SMTP sending solution and can be integrated with other applications, I found it to be quite technical, horrible support and very bureaucratic to start using.

Setup and validation takes forever. I waited almost 1 month for them to validate my account, then they asked for additional information to activate the service. However, during testing everything was simple, after moving from testing to a real application, it was horrible.
