  • Anyone else getting bombarded with invoice spam emails? I’m using a custom domain. These have been relentless for months.
    Sure. I have an account with mailgun, though I have heard good things about sendgrid as well. It costs me $35/mo, but I use the account as part of the management of a phpbb forum I host, but I have a patreon for that that covers the expenses. If I didn't have that patreon, I would have to think pretty hard about how to proceed. Source: about 4 years ago
