SendGrid is competitively priced - as @jamestanderson mentioned, $20 goes twice as far. Mailgun doesn't offer a marketing product at all, and I am not sure if they provide the 24/7 support we do.

At the 40k+ volume levels, you're also going to get a complimentary dedicated IP, which means better deliverability. You can get that at Mailgun too, but it's a $59 surcharge every month.

Finally, the InboxTrail comparison posted elsewhere in this thread shows Mailgun getting flagged as spam 37.5% of the time.

There are many factors that impact deliverability that aren't reflected in the type of simple test InboxTrail conducts. Like most ESPs, your reputation builds on Mailgun as you send with us. If for whatever reason you are experiencing a deliverability problem, you can always reach out to us and we'll help you with any issues you have. We support many large and fast growing customers who are all seeing a >99% delivery rate.

Our support team is here to help 24/7. We have a great team here that is proud of the work we do for our customers.

Disclosure: I lead product development at Mailgun.

As a Mailgun user, I can confirm that first hand.

Yup, me too. I had problems when I started using the service (some providers didn't accept the mail). Everything was immediately resolved.

To respond to the Mailgun developer above slash below - the InboxTrail result might not be reflective of all your service, but you're selling a premium service - 37.5% spam flagging on any of your active IPs is seriously offputting.

We're looking into how that test is being run, but it's not at all reflective of what actual users experience on the platform. There are many factors that could impact what is being sent to spam that aren't disclosed in these kind of tests.

It's true we offer a premium product, but we do so at a competitive price. At scale, our pricing model compares favorably with Sendgrid. Our pricing strategy is all about simplicity and providing lower prices as you grow with us. We don't have any kind of feature gating pushing you into higher tiers nor do we have punitive overages.

As others have mentioned, dedicated IPs are anything but a panacea for deliverability. There is an incredible amount of care and planning that must be taken when using a dedicated IP. Shared IPs that are well managed (ie no spammers) are often better for low-volume senders because they don't require warm-ups, constant deliverability monitoring, etc.
