Amazon SES has one of the most competitive pricings on the market with just $0.10 per 1000 emails.
Pro Barebones service
Amazon SES is created to be a simple service for just sending emails through the API. If you need only to send emails and only that, then Amazon SES should at least be a good contender for your service of choice.
Pro Free tier if using EC2
If you are hosting your web application on Amazon EC2, then the first 62,000 emails each month are free.
Con Has a bad history
When they decided not to support a free tier anymore they've set up a withdrawal period of only 2 months for existing customer before it stopped working (even for people who bought credits to send more than that free tier). Meaning people using it had a month to switch to another solution or start paying $20/month or more.
Con No free plan
There used to be a free plan which offered 12,000 free emails per month. Unfortunately it has now been discounted and there's no other free plan anymore. If you want to use Mandrill, you have to pay $20/month or more.
Con Template rendering doesn't support Handlebars
templates.render call doesn't support Handlebars. This makes complex integrations more difficult. You can, however, use handlebars with
Con Poor error handling
When email could not be received by the recipient due to some failure on their side, SES just drops it. No error recovery, reporting is not that great either.
Con Too lightweight
Since SES has been stripped down to do only one thing and do it well (send emails), there will be a lot of things missing which you will have to add on your own if you wish to have them.
Things like analytics, template hosting, design tools etc... are missing from SES. Although there are third-party tools that allow you to use Amazon SES's API to send emails with all the above features added.
