  • Cold Email Software
    Phplist is free, then you will need to plug that into an SMTP relay like smtp.com or sendgrid.com. Source: over 1 year 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 2 years ago
  • The hell did this user do? They have corp gmail.
    We push customers to smtp.com or mailjet. Mostly because we can pull data from their respective API's directly into our software. Source: over 2 years ago
  • 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: about 3 years ago
