Key Takeaways
- Web unblocking: Settings → More Settings → Security and Privacy → Blocked Addresses → trash icon next to the address
- Mobile limitation: The Yahoo app can't unblock individual addresses — use Yahoo Mail in Safari or Chrome on your phone
- After unblocking: Future emails from that sender land in your inbox again; emails that went to Trash while they were blocked are not automatically restored
- Domain unblocking: Managed separately under Blocked Domains in the same Settings page — Yahoo Mail Plus accounts only
- Blocked list location: Review all blocked addresses anytime in Settings → Security and Privacy
How to Unblock a Sender on Yahoo Mail
Your full blocked list lives in Yahoo's security settings — you can review and manage it at any time.
- Log in to Yahoo Mail on the web.
- Click the Settings gear icon in the top right → select More Settings. (In the new Yahoo Mail interface: click the three dots in the left sidebar → Settings.)
- Select Security and Privacy in the left column.
- Scroll to the Blocked Addresses list.
- Click the trash icon next to the address you want to unblock.
- The address is removed from your blocked list immediately.
What happens after you unblock someone: Future emails from that address arrive in your inbox normally. Emails that went to Trash while the sender was blocked stay in Trash — unblocking doesn't restore them. To retrieve those messages, open your Trash folder and move them to your Inbox manually.
⚠️ Note: If you blocked someone by mistake and their recent emails disappeared from your inbox, check your Trash folder — emails from blocked senders go there, not to a hidden archive.
How to Unblock Yahoo Emails on a Phone
The Yahoo Mail app for iOS and Android doesn't include an option to unblock individual email addresses. Yahoo Mail Plus subscribers can manage Blocked Domains in the app (availability varies by region), but this covers domains only — not specific addresses.
Use your phone's browser
For unblocking individual senders on mobile, use Yahoo Mail through your phone's browser:
- Open Safari (iPhone) or Chrome (Android) and go to mail.yahoo.com.
- Sign in to your account.
- Tap the menu icon → Settings → More Settings.
- Tap Security and Privacy.
- Find the address you want to unblock and tap the trash icon next to it.
This gives you the same access as the desktop version — no app update or Plus subscription needed.
Use Clean Email App on any device
In Clean Email: go to Senders in the left sidebar, then click Blocked in the top menu, find the sender, click on it and choose Unblock.
How to Unblock a Domain on Yahoo
If you've blocked an entire sender domain, it's managed separately from your blocked address list.
In Yahoo Mail (Yahoo Mail Plus only): Go to Settings → More Settings → Security and Privacy → Blocked Domains. Click the trash icon next to the domain you want to remove. Free Yahoo accounts can block up to 3 domains but must use the web interface; Plus supports up to 500.
In Clean Email: If you blocked a domain using Clean Email's Auto Clean rules, go to Auto Clean in the left sidebar, find the rule for that domain, and click Edit → Delete to remove it permanently, or use the toggle to pause it without deleting the rule settings.
Frequently Asked Questions
How do I find my blocked list on Yahoo Mail?
Go to Settings → More Settings → Security and Privacy. Your blocked addresses appear in the Blocked Addresses section. You can review, add, or remove addresses from there at any time.
What happens to emails that arrived while a sender was blocked?
Emails sent while the block was active went to your Trash folder. Unblocking the sender doesn't move those messages back to your inbox automatically — go to Trash and restore them manually if you want to keep them.
How do I unblock someone from Yahoo Mail on iPhone or Android?
The Yahoo Mail app doesn't support unblocking individual addresses. Open mail.yahoo.com in Safari or Chrome on your phone, sign in, go to Settings → More Settings → Security and Privacy, and tap the trash icon next to the address.
Can I unblock a domain in Yahoo Mail?
Yes — go to Settings → More Settings → Security and Privacy → Blocked Domains and delete the domain from there. Free accounts can access domain settings via the web interface; the in-app domain management feature requires a Yahoo Mail Plus subscription.
What's the difference between blocking and unblocking on Yahoo?
Blocking sends all future emails from a sender to Trash and stops them reaching your inbox. Unblocking reverses this — future emails arrive normally again. For full steps on how to block emails on Yahoo, including how to block by domain and what to do when blocked senders keep getting through, see the dedicated guide.
