Signup doesn't allow '+' in the email address, which is sometimes used in Gmail email addresses.

Edit: Plus `## Creating contact lists` in the docs doesn't seem to have rendered properly.

Good catch - That'd be down to the regex in the front end. Will look into it

You shouldn’t use regex for email validation.

The backend (Django) also verifies that the email address is valid. The frontend validation is just added as a an extra convenience

The problem is the standard for what is a valid email address is so varied with enough edge cases that what you might consider a “convenience” is actually breaking the site for other people.

There are quite a number of articles written about this topic, I’d recommend researching it.

Allowing + is bad. It allows users to churn trials easily.

Accept the address and key the user based on the part preceding +.

That can be prevented with simple validation on sign up.

Thanks, appreciate there is still some work to be done on the user onboarding process.

In terms of spam protection, an unsubscribe link is added to all sent emails, to make it harder to spam people. Once unsubscribed, it's impossible to send any more mail to a user.

There's a templates gallery in the app - I'm planning to add a carousel to the landing page to show the possible email themes there
