I'm sure many have already been through this)
Question: how do you notify users about the launch of your project?
For example, on the website there's a page stub with a field for entering e-mail addresses.
On the left users address did you make the emails (on their own with your server)? Or used third-party services? Is there any such? What are the pros and cons?
If the task is simply to collect e-mail with potentially interested parties to notify about the launch (and continue to send them news of the project, for example), the best in my opinion to use MailChimp.
