Which one costs less?

We can't say: Who Sponsors Stuff doesn't publish a Sales Pro price, and its terms bill yearly in advance, so the first number comes from a sales conversation. Book a Sponsor publishes its plans: Starter $19 a month for up to 600 emails a month, Kit $49 a month for up to 1,500 emails a month, Growth $99 a month for up to 3,000 emails a month.

For scale, one main slot in a newsletter with 5,000 to 19,999 subscribers lists at a median $300 (114 newsletters, read 4 November 2026 by Book a Sponsor). Either tool pays back on the sponsors it helps you close, and the difference is who does the sending until then. For more options, see Who Sponsors Stuff alternatives.

When Who Sponsors Stuff is the better pick

You have a salesperson, or want to pitch in your own name: Sales Pro gives direct contacts for decision-makers.
You want to study the market: it shows the ads brands run, with landing pages and tracking codes, and competitive sets by newsletter.
A team shares it: Sales Pro has unlimited seats at no extra cost.
You want a free start: its free plan and weekly newsletter name new sponsors, without their contacts.

When Book a Sponsor is the better pick

You want the emails sent: Book a Sponsor writes and sends the pitches from its own mailboxes, 50 new brands a day by default.
You want a price before a conversation: a plan from $19 a month after the first 200 emails, which come with a $1 card check.
You want a guarantee: first sponsor reply inside 30 days or your money back.

Questions

Does Who Sponsors Stuff pitch sponsors for me?

No. It is a database, so you find the sponsor and send the pitch. Its parent, Email Revenue Solutions, works as an outside ad sales team for newsletters, per its sign-up page; that is a separate service.

How much does Who Sponsors Stuff cost?

The free plan covers about 10% of the database. Sales Pro has no published price: you reach it through a contact form, and its terms bill yearly in advance (read 6 November 2026).

Can I use both?

Yes. A team can research brands in Who Sponsors Stuff and pitch the ones it wants in its own name, and have Book a Sponsor email the rest. Book a Sponsor lets you block any brand you are already talking to.

Which is better for a small newsletter?

Neither states a size minimum. A small newsletter with no salesperson usually gets more from having the pitches sent: Book a Sponsor takes a $1 card check for the first 200 emails, then a plan from $19 a month.

Have the brands that already buy pitched for you

Paste your newsletter. Book a Sponsor lists the brands that sponsored newsletters like yours, finds the person who buys the ads, and emails them every day from its own mailboxes. You get the replies and close the deal.
