Cannot log in to Claude Code: verification emails suppressed for my address, support bot has no escalation path

+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.

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

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.

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.

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.

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.

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.

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.

This is absurd, is Anthropic even addressing this?

It started working again on Monday afternoon. No reply to my support case, no reaction in Github. I agree that this is absurd for a service we're paying for.

I have always had to request a second email before it ever came through, today, not even that is working. Please just let us use a secure password and MFA/Passkey. Having to go to your emails and wait is just ridiculous, especially when they can't be reliably delivered.

Interestingly, I am also based in Brisbane, as OP. I wonder if it is a regional issue.

It's not a regional issue. At least not a Australia regional one. I'm based in Germany.

I have the same issues: authentication mails not coming through and also based in germany. I'd love to have password+mfa, it's a waste of working-time spend with waiting for the authentication mail to come through and https://status.claude.com/ doesnt even indicate that's there an issue going on.

I cannot log in from germany as well anymore. I dont get any verification / authentication emails anymore. I cannot use the fin bot to help me. Cannot contact anthropic ..

Cannot log in from czech republic as well :/

I have the same issue in Romania. The server provider said that the Anthropic IP is blacklisted by SpamCop.

JunkMail rejected - o7.ptr8284.mail.anthropic.com [168.245.101.254]:2298 is in an RBL: Blocked - see https://www.spamcop.net/bl.shtml?168.245.101.254

Of course, is is not just one IP, but a whole pool of them. Even with whitelist of the above one, the next IP is still blocked.

Spamcop IPs for the sendgrid are now cleared again. Now i receive the login link again. My provider blocks when they are listed on spamcop.

All seven are clean now. The four that were listed have all delisted:

149.72.125.152 CLEAN
149.72.89.246 CLEAN (was 127.0.0.2)
168.245.4.162 CLEAN
159.183.66.138 CLEAN
168.245.100.91 CLEAN (was 127.0.0.2)
168.245.101.254 CLEAN (was 127.0.0.2)
168.245.101.31 CLEAN (was 127.0.0.2)

I'm dealing with the same issue in Austria (Pro subscription), and I cannot log in to the CLI for several months. And since it's not an isolated case, it seems like a good use case for an EU-wide legal case - systematic malpractice in not delivering contractual services under EU end-user protection laws.
Do you know if anyone has already initiated it? If not, let's find a proper legal office to have a united claim.

Same lockout, slightly different symptom — recording it here because the
fingerprint matches @martinreichle's comment above almost exactly.

Max subscriber, default_claude_max_20x, active Stripe subscription. Claude Code
on Android/Termux is still signed in and fully working: the refresh token renews
silently against the API with no email in that path. So the account, the org and
the subscription are all demonstrably intact.

The difference from most reports in this thread: I don't get stuck waiting for a
passcode that never arrives. Entering my email returns the "Create your
account" page — as though no account exists for that address. It reproduces on
every device including a private tab on a device that had never signed in, so
nothing client-side is involved.

Fin confirmed in writing it cannot relay to a human, so there is no escalation
path here either.

Hard deadline: the Claude Code refresh token is the only remaining access and it
expires 2026-10-06. After that there is no way back into the account through any
interface.

Filed separately as #95568 with more detail. accountUuid / organizationUuid
available immediately through any private channel — not posting them in a public
thread.

Correction to my comment above — the sign-in method is Continue with Google, not a typed email address, and the trigger was a Claude Code re-login rather than ordinary browsing.

Corrected sequence: Claude Code warned the login would expire, it expired, the re-login (which had worked on every previous expiry) opened the browser, and "Continue with Google" — the same Google address the account has used since 2023, never changed — returns "Create your account".

That makes this a Google-identity-to-account matching failure rather than the undelivered-passcode problem most of this thread documents. Leaving it here since the escalation dead end is identical. Details in #95568.

The issue reappeared after some weeks. The support AI agent reply is completely useless and tries to shift the responsibility to the user instead of Anthropic. At least resending the link five times did eventually work - this is definitely not a state-of-the-art implementation of a login process.

Yes, trying several times is the only thing that helps

On the login page, I see a person sitting behind a desk: he is putting a pencil in his nose and is taken NO attention to what's happening on his laptop. May that be the reason why I don't get a login mail from Claude?

The world is falling apart and this is not helping at all... What a mess!

On random days, I was constantly forced to log back into my Claude Code account over and over again. I experienced this while using Claude Code in VS Code.

Now, because Ukraine attacked Yandex data centers, emails aren't reaching the address registered to my Claude account.

As a Turk, it never crossed my mind that a war would affect me like this. On top of that, Anthropic hasn't provided the slightest solution for this.

I guess people just won't be able to use Claude Code in the event of an email issue.
