We've moved our transactional email away from Mandrill to Mailgun. We had continued using Mandrill after Mailchimp deprecated the service awhile back, because the amount of credits we were offered essentially made it free.

However, following a couple weeks of frequent downtime and poor service transparency from Mandrill, we decided it was time to make the switch. It appears they no longer had any engineers with the ability to identify the core problems.

Mailgun has been more reliable, yet not as reliable as we expected. We still see issues a few times per week with the API failing when we attempt to make a call. The Reporting UI is way better.

This is by far the best way to send emails. I learned the API in under 15 minutes and started sending email right then. And best of all, it's completely free to use them for me! They give you 12,000 emails/month for free. I don't have to send much email, so I've never paid a cent. I highly recommend them.

Very easy to setup, support was helpful, too. The free plan is great for starting out. Used it in conjunction with my cloud hosting on DigitalOcean and had no trouble getting it all setup. Still not doing high volume yet, but so far pleased.

Every app needs email, even the ones we build regularly send some kind, be it signup, reset passwords or general announcements, it's all gotta come from somewhere. SendGrid have been a very reliable platform in the past, and we've had no issues so far.

We use Mandrill to send transactional emails and newsletters. We've just moved from SendGrid as Mandrill has far better support for templates and also integrates really nicely with MailChimp where we can design the emails.

We started off with AWS SES, but found it to be lacking in diagnostics and reporting. Mandrill is a quantum leap forward in this regard. Has some other really neat features carried over from MailChimp (templating).

SendGrid came to our attention as a great way of handling outgoing e-mail communication. Mass capabilities, spam handling and the sheer power of MailChimp as a vendor made our decision here.

All of our external emails are sent using SendGrid. SendGrid's statistics dashboards help us figure out whether our emails are reaching people, and how much attention is paid to them.

Mails from the website frontend are sent through Mailgun, mainly because of the free plan of 10,000 emails which perfectly suits us.
