Spam – can get your SES account suspended

We just had a situation when a bot signed up about 1200 users to subscribe via an email form on our blog. I set the Sendy list to send email asking to confirm email first to be subscribed and this is an email these 1200 users received. Despite the fact that our email asks to delete it if a person did not subscribe saying that they won’t be subscribed if an email is not confirmed – I understand the frustration and why these people marked these emails as spam. As a result, you get in the best case scenario your SES account under review and in the worst – suspended.

I assume this form definitely requires captcha even to enter your email and submit it to subscribe to blog updates and maybe some sort of throttling like https://www.ads-software.com/support/topic/subscription-throttling/ to be production-ready.
