Questions

What is the most used of the email and SMS tools?

Mailchimp, on 543,702 websites in our index (40% of the sites that run any of the 59 we track).

How is market share measured here?

By websites: we read the homepage code of every site in our crawl and count the sites that load each tool. A site that runs two counts for both, so the shares can add up to more than 100%. It's a count of sites, not of revenue or orders.
