Go to Destinations and click Add Destination (or the + button on mobile). This takes you to /destinations/new.
The form
Enter the email address you want to use as a destination. It has to be an address you own and can receive email at — we'll send a verification code there.
Click Send Verification Email. If the address is valid and hasn't been used on your account before, a 6-digit code is sent to that inbox.
After submitting
You're taken to the verification step automatically. The code expires in 15 minutes. If it doesn't arrive, check your spam folder — verification emails occasionally land there.
Enter the 6-digit code and the destination is verified and added to your account. You can start using it on aliases immediately.
If you'd rather not use the code, the verification email also contains a clickable link — clicking it verifies the destination without needing to type anything.
Limits
The number of destinations you can add depends on your plan. You can see your current usage on the Billing page.
If the verification email doesn't arrive
Wait a minute and check spam. If it's still not there, use the Resend email option on the verification screen. There's a 30-second cooldown between resends. After 3 failed code attempts the account is temporarily blocked for 15 minutes — see Can't verify a destination for more.
