None. But it doesn't need them, I think, because it does not send email, it prints an email from a template and a mailing list, then uses mailto[1] to send that to your email client, and you send the templated email from your regular mail client.
Mailto is an protocol like (tel or sms) that invokes a secondary application to send the mail. The way this works depends on how your machine is set up.
For example, on mine it will open my GMail. Before I let GMail handle mailto, it would open my Outlook.
What mail2merge does is take an email template, and a mailing list, and create a mailto link for each one in turn. In order to send that email you need to click the "Do Next Mailto" button, which will open your mail client with the email ready to send. You then need to click send in your email client to send the mail.
I don't know what features Outlook, or GMail, (or any of the other mail clients that you can hook up to mailto), have to prevent spam but presumably they have some. I feel a little scared to say, "the responsibility for spam is with the mail clients, and senders", (because I know how spam is a painful topic and also there's plenty I don't know about how span and email works), but that's how I think about it in this case.
I created this because... I wanted a simple way to send mails from a list, without the complexity and rigmarole of the different mail merge providers. I tried a few GMail add-ons, browser extensions, and "list managers", but they were all too complex. Personally, I also kind of like that I get a "final say" on each mail.
It might be an issue if your list has 20,000 people, but then I guess you can split it and get a couple of people doing it for you.

A slower mail merger, for a more civilized age.
