I'm going to send a lot of (legitimate, not spam) emails, and would like to use an external service provider for this purpose (help track bounce rate, "marked as spam" emails, etc...).
We really need a reliable solution, that would have:
- Very low percentage of lost emails
- No mysterious delays from time of sending to the time the mail is received
- Good bulk API and a high throughput
- Good cost/email is also a factor, though I'd prefer a quality solution over a cheap one.
Which service would you use? What are the benefits of yours chosen solution?
