Problems with registering to my site? (Patreon)

https://www.blitzdrachin.club/The most common problem is that some users aren't getting the ''verification mail'' . We really want to solve this, so if you are having this problem write your mail here please, so we can see if  they have anything in common that might be stopping them. EDIT: It seems that mails that aren't common (with that i mean, that aren't gmail, yahoo, hotmail) have problems to receive mails from the site. We highly recommend you using gmail mails when you register, or using the feature ''register with patreon''
