I’ve actually had good experience using AWS SES for marketing emails. I’ve worked with clients who use it to send hundreds of thousands of emails, and SES is probably by far the best deal you can get price-wise. You just have to make sure that your email list is legit and you don’t get too many bounces or complaints.
By the way: Sending marketing emails is one of the official use-cases for SES:
> You can configure Amazon SES quickly to support
> several email use cases, including transactional,
> marketing, or mass email communications.
> -(https://aws.amazon.com/ses/)
Shameless plug: I’m building an Open Source email marketing tool that allows you to use SES (or plain SMTP, Sendgrid, Mailgun, …) to send mass emails. You can find the repo on GitHub: https://github.com/pentacent/keila
There’s also a hosted version available … and if you’re interested, feel free to drop me a line :-)
