Mailchimp Transactional Email (Mandrill) vs. Zoho Zeptomail

Any system that requires transactional email message functionality as an external service. The benefits of a well managed and vetted server to maintain reputation as well as being reliability is well worth the effort needed to integrate towards the API specs

Incentivized

• Enables transactional email sending via MailChimp which opens up a ton of communication opportunities via Order Confirmation, Cart Recovery, or other transactional emails.
• Monitors sub-accounts send reputation and notifies of high bounce/rejection rates.
• Has a very friendly, usable UI and enables smaller companies to dedicate resources to transactional emails without as much setup work as other transactional platforms.

Incentivized

• Our system adds a notification when a donor has opened an email; however, we've found inconsistencies with the system where a donor may have opened an email, but Mandrill hasn't sent that notification to our app.
• For the scenario above, when we've reached out to their support, the response has been that it is what it is. I'd like to see the supports take be focusing on improving the platform rather than saying it is what it is.

It did the job for us and we were happy with the delivery rates of the email, analytics and customisation available while integrating it within our platform.

We haven't had to use support. The platform uptime is pretty much 100%, and any time we've had an issue, the staff has responded quickly, but honestly, the last time we had to contact Mandrill's support was probably well over a year ago. Once you're up and running, it works.

Sendgrid offers a lot of the same features as Mandrill, but goes a lot further in helping you achieve maximum deliverability for your e-mails. They have a respectable free tier for sending as well as receiving emails, and their paid tiers are very reasonably priced. I don't have as much experience with Mailgun, but they were acquired some-time ago by Rackspace and Rackspace has a reputation for buying companies and not investing additional resources into them. So, at the time of evaluation (a few years ago) their feature sophistication was lagging behind Mandrill and Sengrid.

Incentivized

• Mandrill ensured high deliverability for messages sent to marketing leads in our customer funnel. This was incredibly important for making sure we captured leads early and often.
• Mandrill was a solid and efficient way to send transactional notification messages to customers using our web-based payment system. With online payments, quick response is key, and Mandrill absolutely delivered.
• Mandrill messages meant that our internal team always received notifications about leads, new sales, or problems with our systems in a timely manner. As a small startup, moving quickly was essential and we couldn't afford to miss a beat. Mandrill made sure we didn't.
