How to Stop Receiving Marketing Emails You Signed Up For

How to stop receiving marketing emails is a different problem from stopping spam. If you once bought something from a retailer, downloaded a free guide, or signed up for a discount code, you opted into that brand's marketing list — even if you have no memory of ticking the box. Those senders have your consent, and in almost every case they are required to honour an opt-out when you ask.

This post covers that situation: commercial email from real brands you have dealt with. For newsletters you never subscribed to, or for senders you do not recognise, the right approach is different — see the related posts at the bottom of this page, because clicking unsubscribe on an unknown sender can confirm your address is active rather than remove you from a list.

Marketing emails and transactional emails are not the same switch#

Before you opt out of anything, it is worth understanding the two types of email most brands send. Marketing emails are promotional: sale announcements, product recommendations, newsletters, and loyalty-program updates. They exist to sell you something or keep the brand front of mind. You opted into them at some point, and you can opt out.

Transactional emails are triggered by actions you take: an order confirmation, a shipping notification, a receipt, a password reset, a fraud alert. Under US law these are classified separately from marketing, and senders can send them without an opt-out link, because they exist to serve you rather than to sell to you.

The risk of aggressive unsubscribing — or of using a bulk-removal tool without reading what it targets — is silently deleting transactional mail you will need later: a receipt for a tax return, an order number for a refund dispute, a tracking link for a package en route.

How to stop receiving marketing emails: step by step#

1. 1

   Check the brand's preference centre first

   Log into your account on the brand's website and go to account settings or profile. Look for an option labelled email preferences, communication preferences, or notification settings. Most major retailers, software companies, and media brands have one. From there you can turn off promotional categories while keeping order and account emails on. This is the best outcome: the relationship stays intact and the inbox noise goes away.

2. 2

   Use your mail client's one-click unsubscribe button

   If the sender has added RFC 8058 one-click headers to their email — which most reputable bulk senders now do, following Google and Yahoo's bulk-sender requirements introduced in 2024 — your mail client surfaces a button at the top of the message. In Gmail this appears as Unsubscribe next to the sender name. In Outlook it appears at the top of the reading pane. Clicking it fires the opt-out without loading the sender's web page, so no extra tracking data is shared in the process.

3. 3

   Use the footer unsubscribe link

   If there is no button, scroll to the bottom of the email. US commercial senders are required to include an unsubscribe or manage preferences mechanism under the CAN-SPAM Act. Click the link and you will land on either a confirmation page or the brand's preference centre. Follow the steps to completion — a half-finished opt-out flow may not register as a valid request.

4. 4

   Confirm and keep a record

   Many opt-out flows ask you to confirm your choice, and some ask for a reason. Complete the confirmation step. If the system sends a confirmation email, keep it. The date of that email is your evidence if the mail keeps arriving past the processing window the law allows.

Where each mail client puts the unsubscribe option#

Where your client surfaces the unsubscribe control depends on whether the sender has implemented the RFC 8058 one-click standard or only included a footer link. The table below shows what to look for in each client.

What to do when the opt-out does not stick#

US commercial senders have up to 10 business days after receiving an opt-out request to stop sending, under 15 U.S.C. 7704 (the CAN-SPAM Act, verified via law.cornell.edu). A few emails arriving in the days immediately after you opt out are within that window and do not mean the opt-out failed. Wait out the window before escalating.

If marketing email continues past 10 business days, take three steps. First, email the company's support or privacy team directly, reference the date you first opted out, and request removal in writing — keep the sent message as dated proof. Second, create a filter in your mail client now, before the sender responds: in Gmail, open one of their emails, click the three-dot menu, select Filter messages like these, then choose to archive or delete. In Outlook, right-click the message, go to Rules, and set future messages from that address to move to a folder or the deleted items. This restores inbox calm while the sender catches up. Third, if the sender is a US company and the mail keeps coming after all this, you can report the violation to the FTC at reportfraud.ftc.gov.

One other cause: if you are still getting email after opting out, check whether the sending address belongs to a sub-brand or a data partner the original brand shared your details with. Each entity is a separate sender and needs its own opt-out request.

Handle promotional mail automatically#

Each of those steps works, but the effort multiplies with every brand you deal with. Visiting a preference centre, completing an opt-out flow, and setting up a backup filter takes a few minutes per brand. With dozens of retailers, software tools, and services sending, that becomes a recurring maintenance task rather than a one-afternoon fix.

AI Emaily's Rules Brain can file promotional mail from any sender — or any category of sender — before it reaches your inbox, without a visit to each brand's own settings. When a new promotional sender starts, one rule handles it from that point on. Order confirmations and receipts stay visible because the rule targets sender behaviour and message category, not the whole domain, so the mail you actually need is not caught.

We build AI Emaily. It connects to Gmail, Outlook, and any IMAP-compatible mailbox. You can try it free and set up your first rule in a few minutes.
