What's Wrong?

Problem

I cannot log in to Claude Code (or claude.ai on any new device) because login
verification emails are never delivered to my account email address
(redacted) — spaces added to reduce spam scraping; happy to
confirm the exact address through any private channel).

I am a paying Max plan subscriber. My account is active — I am still signed
in via the Claude desktop app (session active since March 2026, Brisbane,
Australia). If that session ever ends, I will be permanently locked out of
a paid account.

Troubleshooting already done

• Checked Bigpond/Telstra webmail directly (server-side), inbox AND spam:
  nothing arrives, ever. Multiple code requests over several days.
• Contacted Telstra: they confirmed nothing from anthropic.com /
  mail.anthropic.com is being blocked or filtered for my address.
• Verified that Claude emails DO deliver successfully to a different
  bigpond.com address I own (on a separate Claude account) — so this is not
  a provider-wide block. It is specific to my address.
• This same problem occurred once before on this account.

All evidence points to my address being on Anthropic's email suppression
list (e.g. from a past transient bounce).

Support dead end

The Fin support bot (support.claude.com and in-app "Get help") states it
cannot check or modify suppression lists, cannot create tickets, cannot
route to a human, and has no escalation path. It variously suggested
changing my account email (feature does not exist — confirmed by help
article 8452276 and my own Settings page) and deleting my paid Max account.

Request

Please have someone check the email suppression list for my address and
clear it, so verification codes can be delivered again. I can verify
account ownership via my active desktop app session (Organization ID
available on request).

Environment

• Claude Code on macOS (Mac mini)
• Account: Max plan, individual

+1 on this for sure - Verification emails either take a long time (sometimes 15 minutes or longer), then I end up missing the link before the 10 minute window expires because I've moved on to something else. If Anthropic requires the one-click email workflow for login, the emails should be delivered timely and reliably.

[BarisKuzu]

+1 It's incredibly annoying. They changed something and sessions are being invalidated more often than used to and emails take forever to arrive.

[Swemoph]

Honestly guys please just add support for Email + Password + MFA.

Waiting for an email is unreliable and frustrating. It’s crazy that this is the primary auth method.

[Chrius]

I have exactly the same problem. Doesn't matter where I try to login from, it doesn't work. Already checked with the email provider and there's no log of any email arriving... It randomly worked once after a few hours of subscribing, but after that it never worked again.

[vinq1911]

This is extremely frustrating. I find it peculiar that one of the all-time-most-valuable tech companies haven't figured out how to send email. Or, even more, haven't figured out any other way to "securely" log in to their product than email-delivered OTP. Just absurd.

[rigman24]

In our org, we figured out this was being caused by our security scan software triggering on these emails due to the fact that a ~1 trillion dollar company can't seemingly figure out how to properly sign their emails, so it was being flagged by the software. We disabled link-scanning on anthropic auth email, and we get delivered in seconds now. Hope this helps someone else.

[Minzze]

I hope someone else is having the same problem so it helps somebody. I use a @gmail.com address, and for some reason, all Antrotopic emails since August 19, 2026, have been ending up in my spam folder.

[socram70]

It's not in my spam folder and the support is unfortunately useless as it's operated by an AI agent which creates useless replies to my request. Their agent is basically telling me to logout and login again by clicking on the link even though I clearly stated in my support request that I can't login because their emails don't arrive. Their AI-slop support emails obviously arrive though.

[wieluk]

Yea this is a joke. I can not login since this morning. Fin AI support doesn't even let me escalate to a human. I will cancel my subscription when I get back into my account.

Very similar failure mode here, with a different trigger and with
measurements that may help narrow it down.

Timeline (all CEST, 2026-08-23):

• 14:48:39 passcode email sent by Anthropic, received 14:48:49 — 10s delivery
• 14:51:39 passcode email sent, received 14:51:48 — 9s delivery
• from ~15:05 onward: at least five passcode requests, ZERO emails sent
• 21:30 and later: still nothing, more than six hours after the last one

Delivery on my side is provably fine. I monitored the mailbox continuously over
IMAP across all folders during the requests. Other mail kept arriving normally
throughout, including Anthropic's own support replies to the same address at
15:02, 16:34 and 20:32. No bounces were generated. Mailbox is at 9% of quota,
no server-side filter matches the sender, spam folder empty.

So the passcode emails are not being sent at all. This is not a delivery or
filtering problem, and it is not the usual "check your spam folder" case.

Additional data point: my account is demonstrably healthy and in active use. I
am authenticated in Claude Code through an OAuth session on my own server
(subscription type "max", tier default_claude_max_20x) and it refreshes its
token normally against the API — no email involved in that path. So the account
is fine and the subscription is active. The ONLY thing broken is outbound
passcode email to my address, which locks me out of claude.ai, the Claude app,
the Console, and any tool that uses the OAuth login flow. My existing server
session keeps working.

The support path is a dead end, which is the part I think matters for this
issue. The bot replied: "I cannot investigate sending logs, check for
account-level blocks, or remove rate limits. I also cannot escalate this
directly to a team that has those capabilities." The conversation was then
auto-closed with a "Rate your conversation" email. No human ever saw it.

This appears to be hitting multiple users simultaneously today: @wieluk
commented four hours ago, also unable to log in since this morning, also
blocked by the support bot. Combined with my measurements above — emails
delivered fine until 14:51 CEST and then stopping abruptly — this looks less
like an individual suppression-list entry and more like a live incident with
outbound login email. Nothing is currently posted on status.anthropic.com.

Could someone with access to the sending logs / suppression list take a look? I
am a Max subscriber and locked out of my own account. I would rather not post
the account email in a public thread, but can provide it immediately through any
private channel.
