iPhone Mail identifies most junk mail (spam) sent to your @icloud.com address or aliases correctly, but it can mistakenly move our emails to your Junk mail folder.
Periodically check the Junk folder for email messages that were marked as junk mistakenly.
To indicate that an email message from Sermo isn't junk:
- Open your Mail app and go to the Mailboxes screen.
- Scroll down to the folders area.
- Select the Junk folder.
- Find the email from Sermo and slide left to see options.
- Tap the More button.
- Tap the Mark button.
7. Tap the Mark as Not Junk button.
The message is moved to your Inbox. Subsequent email messages from Sermo will no longer be marked as junk.
By default, messages in the Junk folder are deleted after 30 days so be sure to check it often to whitelist relevant email.
