Frequently Asked Questions
mailsac helps and QA teams wrangle their test inboxes seamlessly.
SSO is supported (users must be added to mailsac first).
You can share email test logins, access the same custom domains, manage team API keys, manage sub-accounts, and delegate management of certain tasks.
Email messages are private to your account when using a custom domain or custom private forwarding address.
Sending to any address @mailsac.com works, but it’s public and subject to throttling.
You can send immediately to any address @mailsac.com or @ your custom domain. No need to create the inbox first.
The API supports checking mail for any address, and will return 200 with an empty array if no mail exists there.
To access custom forwarding features (to web socket, webhook, slack, etc), you must “reserve” that address first. This is called a custom private forwarding address.
Companies large and small rely on mailsac to test email workflows as part of their continuous integration pipeline.
We support teams with high uptime requirements, who have integration email tests running 24/7.
mailsac uses standard open protocols like REST, Web Sockets, and Webhooks to allow you to integrate testing pipelines with any system – Jenkins, GitHub Actions, Selenium, GitLab CI, Bamboo, etc – any is supported, as long as it can access mailsac.com.
We have many customers in finance, government, scientific research, and the high tech industries.
In these environments we can provide a copy of our Information Assurance Program, security scanning results, and help you complete a Vendor Risk Assessment (VRA). Note: only supported for our Enterprise plan tier.
We value our relationships with customer of all sizes. About half of mailsac’s customers are enterprise scale. We interact with enterprises on a daily basis.
Purchase order billing is supported on the enterprise plan only.

Single-sign-on is supported via SAML on the business and enterprise plans. Users need to be added in mailsac first, by email address.
There’s some typical SAML configuration necessary in your SSO provider, and in mailsac – you have to swap config. We will support you via email (business plans) and on a screenshare (enterprise plans) if you require assistance.
