  • The 7 best transactional email services for developers in 2023

  • Self-hosted email is the hardest it's ever been, but also the easiest
    Another solution to this problem is relaying through services which will do the heavy lifting for you (this was been discussed in the original thread, here and in the article I wrote).

  • Anyone else getting bombarded with invoice spam emails? Iโ€™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: almost 4 years ago

Another founder noted that without the YC title, it would not have made Product Hunt. A developer who examined Tan's AI-generated website code found 78,400 lines including empty CSS files, duplicate assets, and test files shipped to production. - Source: dev.to / 3 months ago
