Start-here: Transactional + newsletter → Resend (3,000/mo, 100/day, 3 domains on Free). Staging inbox → Mailtrap sandbox (tiny on Free). Marketing audience → Loops. OTP texts → Twilio after trial credit. - Source: dev.to / about 1 month ago
I thought this would be easy using any of the email marketing tools out there like Resend or Loops, but this was not the case. All of the available tools shockingly handle campaigns at a user instead of organization level. - Source: dev.to / 11 months ago
Previously, I used Loops.so to send out newsletters. However, it involved the tedious task of reformatting the blog post within their campaign editor and re-uploading all media. - Source: dev.to / about 2 years ago
