What Does testmail.app's Free Plan Include and What Are the Paid Options?

testmail.app's free plan is a "free forever" tier that includes 100 emails per month, unlimited email addresses and mailboxes, and unlimited collaborators at no extra cost — no credit card required to sign up. Paid plans exist for higher usage and advanced features, but the site's pricing page is the only place to see current tiers and limits, since specific paid-plan quotas and prices aren't listed in the material available here. If your testing volume stays under 100 emails a month, the free plan is likely enough; if you need more throughput or enterprise-level team management, you'll need a paid plan.

What the free plan includes

Based on the site's own description, the free forever plan gives you:

• 100 emails per month — the usage cap that defines the free tier.
• Unlimited email addresses and mailboxes — you generate addresses on the fly by changing the {tag} in {namespace}.{tag}@inbox.testmail.app, so each tag is effectively a new real mailbox.
• Unlimited collaborators — invite as many team members as you need on all plans at no extra cost.
• No credit card required to get started.
• Full API access — the JSON API and GraphQL API, usable from any HTTP or GraphQL client, including CI/CD pipelines.
• Core retrieval features — advanced search with wildcard match, "live" queries that wait for new emails, sorting, pagination, attachments, and SpamAssassin spam reports.
• Security and reliability — HTTPS/TLS forced on all traffic, encryption in transit and at rest, passwordless logins, and APIs backed by a 99.99% uptime SLA.

The 100 emails/month figure is the practical constraint to watch: every test email you send to your inbox namespace counts against it.

What paid plans add

The site points to a pricing page and mentions paid options in a few specific ways, without listing exact tiers or prices in the source material:

• Higher usage — paid plans are the path when 100 emails/month isn't enough.
• Advanced features — the site frames paid plans as offering more, alongside the free tier's feature set.
• Enterprise plan for multiple teams — the free and standard collaboration model lets you invite unlimited collaborators and create separate namespaces per project. The enterprise plan is what you need if you want to manage multiple separate teams.
• Billing — payments are handled through Stripe.

Because the source doesn't publish per-plan quotas or prices, check the pricing page directly for current numbers before deciding. Don't assume the free tier's limits carry over unchanged to paid tiers.

Free vs. paid: how to choose

Choose the free plan if you're testing signup flows, transactional emails, or spam scores at low volume — a handful of test runs per day fits comfortably in 100 emails/month. Move to a paid plan when your CI/CD pipeline sends enough test emails to exceed that cap, or when you need to manage several independent teams rather than one namespace-per-project setup.

Practical notes before you sign up

• Plan your tag strategy. Since each {tag} creates a separate address, you can isolate tests by feature, branch, or run without creating accounts — but every message still counts toward your monthly total.
• Watch the counter, not the mailbox count. Unlimited mailboxes don't mean unlimited emails; the 100/month cap is on messages received.
• Verify current pricing yourself. The free tier's inclusions are stated on the site, but paid-tier quotas and prices are only on the pricing page — treat anything beyond "higher usage" and "enterprise multi-team" as unconfirmed until you read it there.
• Signup is quick. The site says getting an API key takes about 30 seconds, and support is handled by engineers rather than bots, with most priority requests answered within minutes.
