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.

All my personal e-mail (inbound and outbound, personal, transactional and mailing lists) goes through mailgun.

This gives me full control, especially about e-mail addresses: I assign different inbound e-mail addresses for different contacts, so that I can filter SPAM by just blocking the e-mail addresses that leaked out.

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