Affiliate disclosure

Updated Sep 23, 2026.

Where things stand

CallMath has no affiliate agreements with any vendor it lists. No vendor has paid for placement, for a vendor page, or for a comparison.

How vendor links work

Every link to a vendor's website passes through a redirect at pulse.ringlatch.workers.dev/r/ that counts the click and then sends you to the vendor's normal pricing page. The links are marked rel="sponsored nofollow" because we may join vendors' affiliate programs in the future, and we'd rather label them in advance than change them silently.

If we join an affiliate program

• A redirect may then send you to the vendor with a referral code, and CallMath may earn a commission if you buy, at no extra cost to you.
• This page will list every program we join, with the date, before any such link goes live.
• A short disclosure sits next to vendor links throughout the site.

Commissions never change the ranking

The order of results is computed only from each plan's monthly cost at your volume and whether it meets what you asked for. The code that ranks vendors has no commission input, and the data file has no commission field. The formulas are public on the methodology page. A vendor that pays nothing and a vendor that pays a commission are ranked the same way.

This follows the U.S. Federal Trade Commission's guidance that a relationship with a seller be disclosed "clearly and conspicuously", and that "the closer the disclosure is to your recommendation, the better" (FTC's Endorsement Guides: What People Are Asking). That is why the short disclosure appears next to the vendor links, not only on this page.
