    Phplist is free, then you will need to plug that into an SMTP relay like smtp.com or sendgrid.com. Source: about 4 years ago
  • Google workspace vs dedicated IP SMPT
    Let's say I need about 3k emails per day. Is it better to create 3 domains with google workspace or create smpt server and dedicated IP with AWS SES or smtp.com ? Source: over 4 years ago
  • The hell did this user do? They have corp gmail.

  • ProtonBridge, SMTP and Symfony
    Don't abuse ProtonMail for spamming. If you want to spam folks, use dedicated spam services - such as sendgrid, mailjet, smtp.com, Sendinblue, etc, etc. There's a ton of these services who does the spamming in the proper ways. Source: over 5 years ago
