USPS Informed Delivery stopped emailing you (or you can’t sign in): the 2026 fix checklist
If you depend on USPS Informed Delivery to know what’s arriving (checks, DMV letters, prescriptions, packages), it’s a bad surprise when your Daily Digest emails suddenly stop—or when USPS.com refuses to let you sign in with an “Authentication Failed” message.
This problem is widespread because Informed Delivery is heavily used at scale (USPS has published that it sends billions of Informed Delivery emails per year), and even small changes in settings, deliverability, or account status can break what you see day-to-day. [3]
Below is a practical, low-cost set of steps that usually restores Informed Delivery emails and access—plus a couple of “plan B” options so you can still track important items.
The problem (and who it affects)
You’re likely dealing with this if:
- Your Informed Delivery Daily Digest emails stopped arriving, even though you didn’t change anything.
- You can still sometimes see mail previews by logging in, but the email digest is gone.
- The USPS site/app shows errors, or Informed Delivery won’t let you sign in.
- Package or tracking alerts are unreliable, so you’re missing updates.
This affects renters, homeowners, small businesses, and anyone who gets time-sensitive mail (benefit letters, bills, legal notices, replacement cards).
Why this happens (what’s going on)
Based on USPS documentation and how the service works:
1. Informed Delivery emails are a preference you can toggle. USPS describes using your Informed Delivery settings to opt in/out of notification emails (including Mail Delivery Notification emails). [1]
2. Your inbox may be blocking or routing the digest. Sometimes the emails land in spam, promotions tabs, or get blocked by filters—especially after you change email providers, enable new security settings, or mark a message as junk.
3. Account access can be restricted. Users report situations where sign-in errors persist across devices/browsers until USPS support unlocks or fixes the account. (Anecdotal, but common.) [6]
4. USPS notification systems aren’t one single pathway. Even if the Informed Delivery digest is flaky, USPS Text Tracking can still provide package status via SMS as a workaround. [4]
Step-by-step fixes (start with the fastest)
Solution 1: Check the Informed Delivery email setting (it may be off)
1. Go to USPS Informed Delivery and sign in to your USPS.com account.
2. Open your Informed Delivery dashboard.
3. Go to Settings.
4. Look for the option to receive Daily Digest / Informed Delivery email notifications and make sure it’s enabled.
5. Save changes.
Why this matters: USPS explicitly points customers to the Settings page to opt in/out of notification emails. [1]
If you can’t sign in, skip to Solution 4.
Solution 2: Fix deliverability (the email is “arriving,” just not in your inbox)
Do these in order:
1. Search your email for: “Informed Delivery” and “USPS”.
2. Check Spam/Junk, Trash, and any “Promotions” or “Updates” tabs.
3. If you find one, mark it Not spam.
4. Add the sender to your email provider’s safe senders/contacts.
5. Temporarily disable aggressive filters (or create a rule to always keep USPS Informed Delivery messages in your primary inbox).
If you manage email for a business domain, also check:
- quarantine/hold messages
- domain-level spam policies
- whether a recent policy update started rejecting automated digests
Solution 3: Use the dashboard instead of waiting on emails
USPS states you can view Informed Delivery notifications via:
- the morning email digest (when working)
- the dashboard on phone/computer
- the USPS Mobile app (and USPS has also announced a standalone Informed Delivery app planned/rolling out). [2] [5]
If you need the information now (today), the dashboard is often the quickest stopgap.
Solution 4: If the “Get Updates” button or alerts are broken, use USPS Text Tracking
If you just need package tracking updates and the web “get updates” flow isn’t working, USPS Text Tracking can be used directly from your phone:
1. Text your tracking number to 28777 (2USPS).
2. For ongoing updates, text: [tracking number] AA (AA = all past and future activity). [4]
3. If you need help, text HELP to 28777.
4. For additional assistance, USPS provides a Text Tracking help number: 1-800-222-1811. [4]
This doesn’t replace mail previews, but it can keep you informed about packages while you fix the digest.
Solution 5: If you can’t sign in (“Authentication Failed”), ask USPS to unlock/fix the account
If the problem persists across:
- different browsers
- different devices
- clearing cookies/cache
- different networks
…then it may not be “your” device at all. At that point:
1. Call USPS Customer Service: 1-800-ASK-USPS (1-800-275-8777).
2. Ask for technical support for USPS.com / Informed Delivery sign-in.
3. Be ready to confirm identity/account details.
Many users report that a human fix (unlock/reset) was required when sign-in errors wouldn’t resolve locally. [6]

FAQ
1) Is Informed Delivery supposed to email every day?
Typically it’s a daily digest on mail delivery days, and USPS also notes you can view notifications via the dashboard any time. [2]2) Why do I see mail previews but no packages (or vice versa)?
Informed Delivery has separate mail and package components. Also, some notification features can vary by ZIP code or address type (USPS notes certain limitations for some notification features). [1]3) Can I track packages without Informed Delivery emails?
Yes. USPS Text Tracking allows package status updates by texting 28777 (2USPS) and using keywords like AA. [4]4) Will a new USPS Informed Delivery app fix this?
USPS has announced plans for a standalone Informed Delivery app with secure sign-in and notifications. Availability and exact behavior can vary by rollout timing, but it’s worth checking official USPS updates. [5]5) I never changed settings—why would emails stop?
Settings can be toggled off accidentally, an email provider can start filtering the messages differently, or your account access status can change. The steps above address the most common “real-world” causes.Key Takeaways
- Informed Delivery email delivery issues are often caused by settings toggles or email filtering, not your phone/computer.
- Always check the Informed Delivery Settings page first. [1]
- If you need package updates now, USPS Text Tracking (28777) is a reliable workaround. [4]
- If sign-in fails across devices and networks, it may require USPS technical support to fix/unlock the account. [6]
