Where the cheaper entry plan changes

Lite at 500: $12; Essentials is $13 at the same size
Lite at 10k: $120; Essentials is $110 at the same size
Lite at 25k: $280; Essentials is $270 at the same size

Constant Contact Lite is cheaper than Mailchimp Essentials at 500 contacts only. From 1,000 contacts through 25,000, Essentials is the cheaper entry plan wherever both publish a figure.

At 25,000 contacts Lite is $280 against Essentials at $270. At 50,000 and 100,000 contacts Constant Contact leaves the public fee schedule and shows Contact Sales, so those cells stay empty rather than invented. Mailchimp Essentials still publishes $385 at 50,000 and is not sold at 100,000.

Mailchimp SMS is recorded on its own page. Neither SMS meter is inside the email cells above.

What each one counts, and who has a free plan

Mailchimp. Mailchimp's contact table publishes a yes or no per status. Subscribed, unsubscribed and non subscribed contacts all count toward the monthly contact limit. Cleaned contacts, which is where hard bounces land, do not. Pending contacts do not count and are deleted after 60 days if they never confirm. Its free plan covers 250 contacts and 500 emails a month, which sits below the first SideBySend breakpoint.

Constant Contact. No contact counting rule for unsubscribed addresses was visible on the Constant Contact pricing page or inside the fee-schedule modal on the check date. No free plan record sits in this dataset for Constant Contact, so none is claimed here.
