Newsletter advertising that reaches readers who chose to listen
Find newsletters that match your audience, book a dedicated email, sponsored ad or banner, and track every click. Nothing is charged until a newsletter says yes.
What is newsletter advertising?
Newsletter advertising is paying an independent email newsletter to feature your brand in front of its subscribers, either as a sponsored ad inside an issue, a banner, or a dedicated email sent entirely about your product. Because readers opted in to hear from that writer, the ad arrives with borrowed trust instead of fighting for attention in a feed.
For marketers, the appeal is simple: newsletters are organized around a niche. A newsletter about product design, fintech, home cooking or indie games has already gathered the exact people you are trying to reach, and it shows up in their inbox on a schedule they expect. There is no algorithm deciding whether your ad is seen, and no ad blocker stripping it out.
The hard part has always been the buying. Finding the right newsletters, asking for rates, chasing media kits, paying invoices up front and hoping the placement actually ran. LetterBid turns that into a marketplace: listed prices, verified audiences, payment held until the work is approved, and results you can measure.
Everything you need to advertise in newsletters
Matched to your campaign: Describe your campaign and LetterBid suggests newsletters that fit your categories, audience and price, with subscriber counts, open rates and placements side by side.
Verified newsletters: Look for the Verified badge. Those newsletters sent proof of their subscribers, open rates and audience location, and the LetterBid team reviewed it.
Three placement types: Book a dedicated email when you need the whole send, a sponsored ad inside an issue for steady reach, or a banner ad for lighter brand presence.
Listed prices or your own offer: Book a pack at its fixed price, or send a custom offer. The newsletter can accept, decline or counter, with up to 3 counter offers before you agree.
Filtered clicks and cost per click: Every booking gets a LetterBid tracking link that reports filtered clicks, with bots and repeat clicks removed, plus cost per click and click rate.
UTM tags on your links: UTM tags are added to your links automatically, so newsletter traffic shows up clearly in your own analytics alongside every other channel.

Frequently asked questions
Is newsletter advertising worth it for brands?
It often is when the newsletter's readers closely match your buyer. Subscribers opted in and read on a routine, so a well-placed sponsorship can drive clicks and sign-ups from a focused niche. The safest way to find out is to start with a few newsletters, measure filtered clicks and cost per click, and rebook the ones that perform.
How much does it cost to advertise in a newsletter?
Each newsletter sets its own prices, and they vary with audience size, niche and placement type. A dedicated email usually costs more than a sponsored ad or a banner. On LetterBid you see the price before booking, and you can also send a custom offer at the price you want to pay.
What is the difference between a dedicated email and a sponsored ad?
A dedicated email is a whole send about your brand, so it gets the newsletter's full attention for that issue. A sponsored ad is a section inside a regular issue, next to the writer's own content. Banner ads are a lighter visual placement. Each newsletter chooses which ones it sells.
How do I know my ad actually ran?
The newsletter submits a delivery report with the published link, screenshots and results, which must arrive within 5 days. You review it for 3 days and can approve it or report a problem. If the report never arrives, you get a full refund.
Can I see the email before it goes out?
Yes, for dedicated emails. Ask for a preview when you book, and the newsletter sends it before publication. You can approve it or request changes, with up to 2 rounds of changes.
How do I measure results from newsletter ads?
Each booking gets a LetterBid tracking link showing filtered clicks, cost per click and click rate, plus combined stats per campaign. UTM tags are added to your links so the traffic also appears in your own analytics tool.
Does LetterBid add a fee on top of the newsletter's price?
No. You pay exactly the price shown. LetterBid's 25% fee is included in that price and comes out of the newsletter's side, with payment processing included.
What can't I advertise in newsletters on LetterBid?
Ads must be honest and legal. Adult content, gambling, weapons, illegal drugs, scams or get-rich-quick offers, hate content and unlicensed financial or crypto investment offers are not allowed.
