  • SMTP provider without sending\hourly limitation?
    I will confront it with smtp2go, they look very similar, also in terms of cost smtp.com is 10$ more, but we'll see which one suits us better. Thanks for the suggestion! Source: about 1 year ago
  • 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

  • How do people send system messages to (human) clients these days?
    When building apps/websites I often need to send messages to the business owner / admin. The messages range from almost logging type messages such as - "Payment failed for Order 123, please manually process the transaction" to generic contact forms on a website: - "FirstName LastName sent a message with the following text: something something something" My knowledge is rather old and currently I just send email... - Source: Hacker News / 7 months ago
  • how I got customer onboarding right
    Sendgrid, Mailgun, or Postmark are great solutions if you have a need for transactional emails that are technical. I still prefer using Customer.io for this need. If you’re unsure what transactional emails are, check out this guide. Source: 8 months ago
