Tockify VS Landing Pages in MailChimp

Tockify looks like one of the few solutions that would work that has a free version. I've never used it, but it's mentioned in a few "embeddable calendars" articles. Source: over 1 year ago

You can change the colors a bit, but that's about it. To do anything more you need an integration code and things won't look good on mobile without more coding help. There are options like tockify.com and http://upto.com/ that will do this all for you, but they cost money. Source: almost 2 years ago

Your example is actually the only time I've ever seen this side-by-side-style login page with the form on the right. Mailchimp, Quickbooks, and Alliant CU, for example, use the same layout as OP. I'd guess that Rippling is really trying to push their marketing, which is why it's on the left. Source: over 2 years ago

And, of course, you need a Mailchimp account. If you still haven’t had an account, create a new one here. - Source: dev.to / about 3 years ago
