Periodically email or call the companies and ask to be removed from their mailing lists (check their privacy policy page for exact opt out contact details). This is the most effective way to get off mailing lists.
Write on the note, "(Former Resident's Name) does not live at this address". Place the note on the inside of the door or the mailbox itself. This will serve as a constant reminder to the postal carrier to look through the incoming mail and remove any of the previous resident's mail that they might be about to deliver.

Many of the companies who send you advertising in the mail are members of Direct Marketing Association (DMA). You can register with them to be removed from their member's mailing lists. They also make their “Do Not Mail” list available to some non-members.
Removing someone from your email list is very simple, and depending on the email client or marketing tools you use, the process of removing them is relatively the same. Go to your contacts, lists, subscribers, or audiences. Place a checkmark by each contact you want to remove. Choose to unsubscribe, or delete.
The quickest way to unsubscribe from emails is to use the "Unsubscribe" link typically found at the bottom of marketing emails. Clicking this link automatically removes you from the mailing list. Alternatively, use email management services or apps to streamline the process.
Dear Sir/Madam, This is a request that my personal information is removed from all of your mailing lists for unsolicited mail. I would like my name and address removed, effective immediately. You are currently sending unsolicited mail to: insert name, address, and zip code.
The most effective way to stop receiving mail for previous residents or strangers is to talk to your local Post Office. Most of the time, you'll be able to quickly resolve any issues by listing your household members as the only people who should receive mail at your address.
