Hi there,

Thank you for your feedback! We are doing our maximum to ensure best delivery. All you need to do is to reach support@emailit.com in case you have delivery issues. As we need to verify you and move you to a high-reputable IP pool.

I am not aware of any domain restrictions; you can use any domain for which you can set DNS records. (as with any other email providers).

We are sorry for your bad experience, as it is definitely not something we want you to have! Feel free to reach out to us anytime on our support email or Discord, so we can help.
