Questions

What counts toward the email limit?
Every email delivered to one of your team's addresses, temporary or permanent. The count resets every month. Once the limit is reached, new mail is not stored until the reset or until you upgrade.
What is the difference between temporary and permanent inboxes?
Both use the address format {teamId}.{anytext}@zyntramail.com. A temporary inbox needs no setup: send to any address and read it over the API; its mail is kept 1 day. A permanent inbox is one you create in the dashboard: you can read it in the web viewer too, and its mail is kept as long as your plan says.
Why does Free have a limit of 500 API requests?
Every read of an email is one request, and so is every list, attachment or delete call. The Free limit is enough to try Zyntra in a suite; a suite that runs in CI every day needs a paid plan.
How do I upgrade or cancel?
Start on Free and upgrade from the dashboard when you need more. Cancel there at any time: the plan stays active until the end of the period you paid for, and is not renewed.
How is the yearly price billed?
Once a year, upfront: twelve times the monthly figure shown for yearly billing.
