Current opt-out methods for Comcast Business mail
-
Promotional mail preference form
Open Comcast’s Opt Out preference center. Select Business as the request type. Check Promotional Mailing and enter your full name and service address. Comcast states you may still receive promotional mail within 60 days, then mail should stop for that address.
-
Email request
Use the Email option on this page if you need to follow up in writing. The published business preference form remains the primary path.
If sending your opt-out request by email, use this helpful template for Comcast Business:
Hello, I'm writing to request that Comcast Business permanently remove my address from all direct mail lists, including your internal house list and any rented or third-party lists used to source your mailings. The name and address to remove as they appear on a recently delivered unwanted mailer: [NAME] [ADDRESS] [CITY ST ZIP] A few notes for your direct mail team: • I have never subscribed to marketing communications from Comcast Business. • This address is registered with the National Do Not Mail list (DMAchoice), so standard list hygiene should already be suppressing it. • Since I haven't opted in with you directly, the source is most likely a rented or co-op list. Please also flag this address with your list partners so it's suppressed at the source. Please confirm in writing once the suppression is complete. I've attached an image of the mailer for reference. Thank you, [NAME]
Replace the bracketed fields ([NAME], [ADDRESS], [CITY ST ZIP]) before sending. Attach a photo of the mailer if you have one, and keep the reply for your records.

What to Expect After Opting Out
Allow 8 to 12 weeks, and note Comcast’s 60-day promotional-mail window on the preference form. Business service bills, install notices, and account mail can continue. This opt-out targets promotional mail about new products, not invoices for active service. [Xfinity](/stop-junk-mail/xfinity-comcast/) is the sister consumer brand if residential mail is the issue.
Why Do You Receive Comcast Business Mail?
Comcast Business is the commercial arm of Comcast, selling internet, voice, and network services to small businesses, enterprises, and the public sector. It shares marketing infrastructure with the broader Comcast footprint, which is why a business address can receive product promos even when service is consumer [Xfinity](/stop-junk-mail/xfinity-comcast/) at home.
You see this mail if your company is a prospect, a former lead, or a current customer whose account still qualifies for product marketing. Telecom vendors mail aggressively after fiber or coax builds in a zip code.
How to Prevent General Junk Mail Proactively
DMAchoice can reduce other national commercial mail. Comcast participates in ANA programs, so DMAchoice may help on some unrelated marketers but is not a substitute for the Comcast preference form above.
OptOutPrescreen opts out of prescreened credit and insurance offers.
NOTE: OptOutPrescreen will not opt you out of Comcast Business mail. It only covers prescreened credit card and insurance offers.
PaperKarma opts out of individual telecom promos when you photograph the mailer.
Your Data Privacy Rights (CCPA & Beyond)
Marketing opt-out through the preference center is separate from state privacy deletion or do-not-sell requests. Use Comcast Business privacy pages on business.comcast.com for those rights. Do not use a gated marketing inbox for CCPA requests.
