Mailtrap alternative: when you need to receive, not capture
Mailtrap is an SMTP sandbox: your app sends through it and the mail never reaches a real address. That is the right tool for checking your own templates. It cannot receive an email another service sends to a test address, which is what signup, OTP and vendor-login testing need.

Who this is for
1Teams testing signup on a production or third-party service
2Developers who tried to receive an OTP in a Mailtrap sandbox
3QA who need one tool for outbound capture and one for inbound receipt
In short
Inflovy is the Mailtrap alternative for inbound testing: a real, receive-only inbox that any third party can email, with the verification code extracted on arrival. Use Mailtrap to inspect what your app sends; use Inflovy when a test account on another service (Stripe, Auth0, a vendor portal, your production app) must receive and confirm an email. Free to start; API from $12/month (September 2026).
What an SMTP sandbox cannot do
It only sees mail your own app sends through its SMTP credentials.
It cannot receive the confirmation email a vendor, an OAuth provider or your live app sends to a test address.
Free tier is 50 test emails a month with 1 user; Basic is $14/month for 3 users (September 2026).
What a real test inbox does
A routable address on inbound.inflovy.com that any sender can reach.
Verification code and links extracted from every message.
Team-visible inboxes and a wait endpoint for tests.
Receive-only, so it can never be misused to send.
Mailtrap versus Inflovy.
Two different jobs; many teams use both.
| Need | Mailtrap (Email Sandbox) | Inflovy |
|---|---|---|
| What it tests | Email your app sends (templates, headers, spam score). | Email your test accounts receive from anyone. |
| Receive from a third party | No. | Yes: that is the product. |
| Free tier | 50 emails/month, 1 user. | 10 inboxes, 3 members, 200 messages/day. |
| Entry price | $14/month (Basic, 3 users). | $12/month (Pro, 5 members, API). |
| OTP extraction | No. | Yes, on every message. |
Who should pick which
Stay with Mailtrap if
- You are checking how your own transactional emails render
- You need spam-score and HTML-compatibility analysis
- You want a sending API for production
Choose Inflovy if
- A test account must receive an email from another service
- You need the verification code without opening the message
- The whole team should see the test inboxes
Questions people ask before switching.
Short answers. Inflovy is a receive-only test inbox for developers and QA teams; it does not replace your mailbox or send anything.
Can I use Mailtrap and Inflovy together?
Yes, and many teams should: Mailtrap for inspecting outbound templates in development, Inflovy for receiving real mail on test accounts in staging and production.
Can Inflovy inspect my outbound email like Mailtrap?
Only if you send it to an Inflovy inbox. It shows the rendered HTML and the snippet but does not do spam scoring or client-compatibility previews.
