Gmail’s Block command sends future messages from that sender to Spam. It does not reject their email or permanently delete it on arrival. A message in Trash has been deleted or moved there by another action, such as a filter. Google explains sender blocking.
Block, filter and delete forever do different jobs
| Action | What changes | What remains |
|---|---|---|
| Gmail Block | Future mail from the sender goes to Spam. | The message can still be seen in Spam. |
| A filter with “Delete it” | Matching mail goes to Trash. | Trash is still part of the mailbox until permanent deletion. |
| Delete forever | Removes selected messages permanently. | It does not create a rule for future mail. |
| Unsubscribe | Asks a mailing list to stop future messages. | It does not erase existing messages or control an uncooperative sender. |
Google automatically deletes Spam after 30 days, and Trash after 30 days in that folder. These are separate processes: Spam is not a mandatory waiting room before Trash. You can delete sooner, but permanent deletion removes the normal recovery option. See Spam controls and Trash and permanent deletion.
Check the folder before changing the rule
- Check which Gmail account received the message. A rule in one account does not configure every account.
- Inspect the sender’s actual address. A display name is not an email address; a different address may need a different rule.
- If the message is in Spam, that is consistent with Gmail Block. If it is in Trash, inspect filters and other connected mail tools.
- If the message remains in the Inbox, review Filters and Blocked Addresses and the specific message’s sender. Do not assume a block covers every address a person may use.
Where BYE! fits—and its current limit
BYE! is a Chrome extension for sender-based Trash cleanup and separate Spam/Trash clearing. In the inspected 0.1.8 code, adding a BYE! sender rule creates a Gmail filter that adds Trash and removes Inbox. The extension’s scheduled cleanup searches Trash for configured senders and submits matching message IDs for permanent deletion.
The automatic search is restricted to Trash. The option that includes Spam and Trash in the API search does not remove that Trash restriction. Mail already sitting only in Spam is not covered by this automatic query. The separate Spam-clearing control targets the selected accounts’ Spam folder broadly; it is not a sender-only operation.
That makes “never appears anywhere” and “automatically clears every folder” inaccurate descriptions of the inspected version. Cleanup also depends on a running extension, sign-in, valid Google authorization, network access and BYE!’s backend. Messages can remain visible before a successful cleanup.
Choose the smallest action that solves your problem
If keeping mail out of your Inbox is enough, Gmail Block may be sufficient. If you want selected messages gone now, use the sender-deletion guide. If you are considering automation, review its folder coverage and permissions before connecting an account. For a work or school mailbox, an administrator may have server-side rejection controls unavailable to personal Gmail users.
Evidence note: Gmail behavior is documented by Google. BYE! statements here come from inspection and isolated tests of extension 0.1.8 on September 12, 2026; a live Gmail deletion test has not yet been completed. This guide is published by BYE!’s maker.
