About
Markettrellis writes about marketing software for people who are about to pay for a subscription and want the price in plain units.

The categories are search, content, social, email, customer records, automation, analytics, and AI features. Mailchimp and HubSpot are named with prices because their pages state them clearly. Mailchimp Standard starts at $20 a month for up to 500 contacts. HubSpot Marketing Hub starts at $20 a month per seat, then $890, then $3,600. Other tools are described by the job they do. Their current price is on their own page.
Markettrellis is not an agency and does not run campaigns. The next step after a note here is the company's site.
