Receive/send sometimes have failed & marked as spam
Was using free tier, some people said they couldn't send me emails. Probably they're getting bouncebacks? The emails I sent to them occasionally got marked as spam or just didn't get sent. Missed a few business related emails because of this and caused a lot of confusion. After upgrading to paid tier this problem hasn't occurred again yet, but it'd be great to be informed about potential problem I can face in the free tier, and I'm pretty sure I will make a switch if this happens again with the paid tier. For the record I've done everything the site told me to do, like SMTP and fiddling with the DNS settings.

Hi there, We appreciate you taking the time to provide feedback about your experience. We understand the frustration of encountering deliverability issues. Regarding receiving and forwarding emails, if you encounter any problems, please reach out to our support team directly. We're happy to offer support to all our users, even those on the free plan. Regarding sending emails, you're correct that the free plan uses Gmail's SMTP servers, which don't include SPF or DKIM support. This can impact email deliverability, as some recipients' email systems might flag emails without these as potential spam. We do our best to explain this limitation on our website and in our newsletter. Our paid plans use ImprovMX SMTP, which includes full support for SPF, DKIM, and DMARC, leading to significantly better deliverability. With ImprovMX SMTP, we also leverage a vast pool of IP addresses alongside a unique retry mechanism to ensure your legitimate emails always get through. We're glad to hear the paid plan has resolved your sending issues. If you face any similar problems in the future, please let us know. Thank you for your understanding and continued use of ImprovMX!
