MailgunvsRevue

Overview

Mailgun is a transactional email sending API for developers. Engineering teams use it to send application-triggered email — password resets, order confirmations, and account notifications — via SMTP or HTTP API, with delivery analytics, bounce handling, and email validation built in.

Revue was a newsletter platform owned by Twitter. It allowed writers and creators to build a subscriber list and send regular email newsletters, with paid subscription support tied to Twitter accounts. Twitter shut down Revue on January 18, 2023. All newsletters, subscriber lists, and content were permanently deleted. Revue is no longer available as a product.

This comparison explains what each tool was, how they were different, and what newsletter creators should use now that Revue is gone.

Feature Comparison

Mailgun is API-first email infrastructure. Developers integrate it into applications via HTTP API or SMTP. The dashboard shows per-email delivery logs, bounce classification, spam complaint rates, and domain reputation metrics. Email validation checks deliverability of an address before sending. Inbound routing receives email on a custom domain and forwards it programmatically. Mailgun handles high-volume transactional sending reliably — it is not a tool any individual writer would open to compose a newsletter.

Revue had a newsletter writing interface with a clean editor, subscriber list management, and paid subscription support via Twitter's payment infrastructure. Newsletters were distributed to subscribers via email and discoverable through Twitter profiles. The integration with Twitter gave Revue reach within the Twitter ecosystem that most newsletter platforms lacked. Revue did not offer advanced marketing automation, segmentation, or multi-channel messaging.

The tools do not overlap in meaningful ways. Mailgun is developer infrastructure for sending application email. Revue was a publishing platform for human-written newsletters. The only intersection was that newsletter platforms at scale — including infrastructure powering products like Revue — use transactional email APIs like Mailgun under the hood for reliable delivery.

Pricing Comparison

Mailgun's Foundation plan starts at $35 per month for 50,000 emails. A free tier covers 100 emails per day. Growth at $80 per month covers 100,000 emails with extended log retention. Verify current pricing at mailgun.com.

Revue was free for newsletter creators. The platform took 5% of paid subscription revenue as its fee. There were no monthly subscription costs for creators.

For newsletter creators now seeking a Revue replacement: Substack (free, 10% of subscription revenue), Buttondown (free up to 100 subscribers, then $9–79 per month), beehiiv (free up to 2,500 subscribers, paid from $39 per month), and Kit (free up to 10,000 subscribers, paid from $25 per month) are the primary alternatives. All offer paid subscription support and newsletter delivery without the Twitter dependency that made Revue a platform risk.

Best For

Mailgun fits development teams building applications that need programmatic transactional email sending. SaaS products, e-commerce platforms, and developer tools use Mailgun for password resets, receipts, and user notifications.

Revue replacements — Substack, Buttondown, beehiiv, or Kit — fit writers, journalists, and creators who need a newsletter publishing platform with subscriber management, paid subscriptions, and reliable email delivery to a public audience.

There is no scenario where a newsletter creator evaluating Revue alternatives should evaluate Mailgun. These tools serve fundamentally different audiences and use cases.

Verdict

Winner: Mailgun in the sense that Mailgun is a functioning product and Revue is not.

For newsletter creators displaced by Revue's shutdown: the right category is newsletter platforms, not transactional email APIs. Substack, Buttondown, beehiiv, and Kit are purpose-built for the use case that Revue served. Any of these is a better fit for a newsletter writer than a developer API like Mailgun.

For developers evaluating email infrastructure: Mailgun competes with Amazon SES, Postmark, and SendGrid — not with newsletter platforms. The choice between them comes down to feature breadth, deliverability reputation, and cost at volume.
