Mandrill vs Postal: What are the differences?
What is Mandrill? Send transactional, triggered, and personalized email, then track results. Mandrill is a new way for apps to send transactional email. It runs on the delivery infrastructure that powers MailChimp.
What is Postal? Open source mail delivery platform, alternative to Mailgun or Sendgrid. Postal is a complete and fully featured mail server for use by websites & web servers. Think Sendgrid, Mailgun or Postmark but open source and ready for you to run on your own servers. Postal was developed by aTech Media to serve its own mail processing requirements and we have since decided that it should be released as an open source project for the community.
Mandrill and Postal can be primarily classified as "Transactional Email" tools.
Postal is an open source tool with 9.02K GitHub stars and 533 GitHub forks. Here's a link to Postal's open source repository on GitHub.
For transactional emails, notifications, reminders, etc, I want to make it so writers/designers can set up the emails and maintain them, and then dynamically insert fields, that I then replace when actually sending the mail from code.
I think the ability to use a basic layout template across individual email templates would make things a lot easier (think header, footer, standard typography, etc).
What is best for this? Why would you prefer Mailgun, SendGrid, Mandrill or something else?
If you need your emails to be sent in a time-sensitive manner, I'd recommend SendGrid. We were using Mailgun and the lag because they aren't "transactional" in nature caused issues for us. SendGrid also has the ability to do dynamic templates and bulk send from their API. I don't know that they have the shared layout ability you mentioned, though.
The only transactional email service that I've been able to stomach is Postmark! It is by far the easiest (and quickest to get feedback from) service that I have come across. While drowning in attempts to debug Mandril, Mailgun and others I get quick feedback from Postmark in what I need to do.
Postmark for the win!
We are using more extensively Mandrill.
It is a ok tool, which gives you the power for emailing with nice set of features.
The templates editing and management is a bit tricky, but this is mostly related to email templates in general, which are hard to create and maintain.
I do not think you can share the parts of the templates. You can have your predefined templates with possibility to insert dynamic content.
They provide a limited possibility to preview and test your templates.
The template editor is text only. For the better editors checkout http://topol.io or https://mosaico.io
Unfortunately, I do not have experience with the other tools and possibilities to manage templates.
At this stage, all of the tools you mentioned do email delivery pretty well. They all support email templates as well. Here are some considerations:
- Twilio owns SendGrid. If you're an existing Twilio customer, in my opinion that's a good reason to use SendGrid over the other solutions. The APIs are solid, and Twilio has excellent developer tools that allow you to create interesting automations (which is important for scaling).
- Mandrill was created by MailChimp, who have massive experience with email delivery and specifically with emailing beautiful email templates.
- Mailgun is a tool on its own. Like the other two, it supports mail templates and is built to be controlled almost exclusively via APIs.
SendGrid and Mandrill have pretty nice WYSIWIG template editors as part of their platform. Not so sure about Mailgun.
So for me the considerations would be: 1. How easy is it for you to integrate with their API? How complete is their API in terms of your own specific needs? 2. Prices: Which one works best for my budget? 3. Am I OK with editing the templates elsewhere (or even by hand), and then pasting the code into Mailgun? Or do I want the comfort of Mandrill or Sendgrid with their WYSIWYG editors?
Personally I'd go with Twilio, simply because it's such a massive ecosystem they are less likely to go bankrupt, and their APIs are rock solid.
We did a quick test on the reliability of these three common email services, sending a few emails an hour at random intervals.
Unfortunately, none of them had 100% availability over the 30 day test. I don't understand why this is so hard?
Mailgun performed the best with the most reliability and fastest response times. Mandrill was notably bad.
