The ranking is the answer; these are the words behind it. Every quote is from a recorded model answer — follow the category to read it whole.
MailerSend
MailerSend — A very good developer-friendly middle ground for transactional email, particularly if you want built-in address validation, real-time reputation/activity monitoring, and more hands-on deliverability support than SES.
ChatGPT
SendGrid
Twilio SendGrid — Still a credible, proven enterprise-capable platform with useful mailbox-provider, bounce/block, complaint, and inbox-performance visibility, though I would generally choose Postmark or Mailgun first for a new deliverability-sensitive implementation.
