Frequently asked questions

Do I need an account to receive email online?

No. Public temporary inboxes open directly by address.

How quickly will a message arrive?

Delivery depends on the sender and mail network. New messages appear after they reach iSealMail.

Why did a verification email not arrive?

The sender may delay delivery, block temporary domains, or have the wrong address. Recheck the address and try another enabled domain.

Can other people read the online inbox?

Yes if it remains public and they know the address. Claim it privately when exclusive access matters.
