Why your school email can block the link.
Some university inboxes filter out sign-in links before they ever reach you. It isn’t your fault, and it isn’t Atlas. Here’s what’s happening, and the fastest way around it.

Held by security filterYour inbox is trying to protect you.
School mail systems are tuned to be cautious. The same machinery that stops phishing can also stop a one-time sign-in link.
Scanners open the link first
Filters like Microsoft Defender, Mimecast, and Proofpoint “click” every link to check it’s safe. A magic link works only once, so that automated scan can spend it before you do.
Quarantine and delays
Sign-in emails from outside your school are often held for review or dropped into a quarantine you never see, so the link lands late, or never arrives at all.
Strict external-sender rules
Some schools block mail from new senders outright, or rewrite the links in a way that quietly breaks them before you ever tap one.
Four ways in, fastest first.
- 1
Use a personal email
RecommendedSign in with a Gmail, Outlook.com, or iCloud address. It’s the most reliable way in, and you can still add your school and program to your profile afterward.
- 2
Continue with Google
The Google button skips email links entirely. If your school runs on Google Workspace, it usually just works.
- 3
Check junk, spam, and quarantine
Used a school address already? The link is often sitting in a filtered folder. Search your inbox for “Atlas” before trying again.

Resend, then give it a minute
Filters sometimes wave the second message through. Tap Resend, wait about 60 seconds, and use the newest link, older ones expire.
Still locked out?
If none of these get you in, email us and we’ll sort it out with you. Tell us the address you tried and your school, it helps us spot what your filter is doing.
