Which Should You Choose?

Choose Mailgun if you build software that sends its own mail and want inbox placement tests and address checks under the same login. Choose MessageFlow if you run email, SMS and push for European customers from one panel. Mailgun is bought on a free plan first, with paid plans after that, billed monthly. MessageFlow is sold as paid monthly plans, with higher plans sold by quote.

Developers who wire email into an application get the most from Mailgun. A sandbox mode lets test calls run and report events while nothing is delivered. Scheduled delivery queues a message for later, and inbound parsing receives mail sent to a domain and posts the result to the application. The sending application decides the content and timing of every message. Newsletters built in a drag and drop editor belong to Mailjet, a companion product from the same owner.

Notification and marketing mail share one panel in MessageFlow. It adds SMS and mobile push as their own channels beside email, and one set of APIs sends them all. A drag and drop creator builds campaigns, and an assistant drafts their subject lines. SMS targets Polish numbers out of the box, and sales staff verify any other destination first.

Mailgun describes an ecommerce marketing platform that runs sending and sender verification for its merchants, and that customer could remove a domain verification email flow it never needed. One MessageFlow customer, a retailer of home decor, sells in shops and on the web. It moved its SMS campaigns off a foreign provider to cut cost, and added an email API and RCS. Its SMS campaigns convert far better than the e-commerce norm, the vendor reports.
