FAQs
-
Mailchimp has a higher average inbox placement rate at over 99%, compared to Mailgun's 98%. That gap may sound small, but across millions of sends it adds up to tens of thousands of additional messages reaching customer inboxes.
Strong deliverability matters most when using transactional emails for password resets, order confirmations, and shipping updates, where a delayed or missed send can frustrate customers and create support tickets.
-
When it comes to Mailchimp Transactional vs Mailgun for high-volume sending, Mailchimp is the better fit for most teams because its pricing is predictable. You purchase blocks of emails at a set rate, so your monthly costs stay steady even during busy sending periods.
Mailgun uses a plan-based monthly allocation model that charges overage fees once you pass your plan's included volume, which can lead to extra charges when the send volume spikes.
-
Mailchimp lets you manage transactional emails and SMS together inside the same account, so your customer communications live in one place alongside your marketing tools. Mailgun's own platform doesn't send SMS natively.
To add text messaging, customers typically connect to Sinch's separate messaging products or build a gateway through a third-party SMS provider using tools like Zapier, which means a second account, extra setup, and another vendor relationship.
For teams that want a single login and a unified experience, Mailchimp is the more straightforward Mailgun alternative.
-
Mailchimp is the easier option for anyone who isn't comfortable writing code. Mailchimp Transactional includes a visual template builder that lets marketers, designers, and operations teams create, edit and manage transactional templates through a drag-and-drop interface in Mailchimp.
Mailgun leans heavily on code, and most setup and template work happens through APIs or raw HTML, which usually requires developer time.
-
Yes. Mailchimp Transactional is an add-on to a paid Mailchimp Marketing plan, not a standalone product.
The upside is that you get both marketing emails and transactional sending from one account, which supports a more unified approach to transactional marketing and gives your team a single place to manage campaigns, automations, and receipts.
-
When weighing Mailgun or Mailchimp on support, Mailchimp comes out ahead. Every paid Mailchimp plan includes 24/7 live chat support, so you can reach a real person whenever an issue comes up.
Mailgun restricts its lower tiers to ticket-based support, which means longer wait times and no direct conversation when something urgent happens. For teams sending time-sensitive messages, that gap can affect how quickly problems get resolved.
