How do you use a profile?
- Open the profile index. All 430 profiles, by name. Done when you have the brand you want.
- Read where it advertised. Look for newsletters like yours and how recent the last ad is. Done when you know whether it buys in your niche.
- Check the brands beside it. Brands that sponsor the same newsletters are often worth a pitch too. Done when you have a short list.
- Pitch it, or have it pitched. Write the email with the request letter generator, or let Book a Sponsor send it on a plan from $19 a month. Done when the email is out.
What are the limits?
- A profile shows ads we found in published issues and on newsletters' sponsor pages. A placement that never appears in either isn't counted.
- Brands under 5 newsletters, or with no recent ad, have no profile. The full list has 8,550 brands across 4,988 newsletters.
- No prices: a profile says where a brand advertised, not what it paid. For prices see newsletter sponsorship rates.

Questions
Where do the profiles come from?
From the published issues of newsletters we read. Each "sponsored by" or "brought to you by" block is recorded with the newsletter and the date.
Why is a brand I know missing?
A profile needs 5 or more newsletters and a recent ad. A brand under that is still on the full sponsors list, and it gets a profile once it has a recent ad in 5 or more newsletters.
Can I see who to email at the brand?
Not on the profile. A free run on the home page shows the buyer at the top brands for your newsletter, masked, and Book a Sponsor emails them for you after checkout.
How do I use a profile in a pitch?
Name a newsletter like yours that the brand sponsored lately, and say why your readers fit. The request letter generator fills that in.
