You do not need the email to use your eSIM. Everything in it is also in the app, under your eSIMs. Install from there and you are connected. See "Find your QR code and activation details again".
If you would still like the email, work through these in order.
- Search your whole mailbox, not just the inbox, for "SimFuse". Filters and promotions tabs catch it more often than spam does.
- Check the spam or junk folder and mark the message as "not spam" so later ones arrive normally.
- Check the address for a typo. One wrong character at checkout sends the email nowhere. If you can sign in and see the order, the address on the account is the one we used.
- Check whether you used a hidden email address. Sign in with Apple can create a relay address, and mail sent to it can be filtered before it reaches you.
- Corporate mail filters strip messages with links fairly often. A personal address avoids this.
Once you can sign in, you can resend the details to yourself from the order at any time. If none of the above works, contact us and we will send it to an address of your choice.
