First off: the Seller.Tools team would 100% recommend upgrading to a PRO plan. It unlocks a huge number of powerful features for a relatively low investment, and you can't use ST + MC without a Pro plan!
Does Free have unlimited subscribers? Is there a limit for anything else?
Yes, free accounts do have limitations. You can have as many subscribers as you'd like, but free plans offer access to a limited number of Tools and bot elements.
What do I get precisely with the PRO subscription in terms on new instruments?
First and foremost, you will have no limit in creating new Growth Tools, Sequences, Tags, and Custom Fields.
Then, you will get access to the JSON Growth Tool, Facebook Messenger Code, External Requests, and Checkbox. With that, you will be able to connect Integrations now: Seller.Tools, Zapier, Integromat, Google Sheets, and MailChimp.
Pro plans also do not have subscriber limitations, but your monthly subscription cost will increase accordingly with additional subscribers.
