Email is the best way

For support questions, technical issues, feature requests, billing problems, or anything else — email is the most reliable way to reach us.

We aim to reply within 24 hours on weekdays, and within 48 hours on weekends. If you haven’t heard back in 3 days, please send a follow-up — very occasionally messages get caught by spam filters.

Email us within 14 days of payment if your annual subscription doesn’t feel right. We’ll help.

I’m a teacher and want to share Sussed with my class.
Email us — we’d love to hear what you teach, what year groups, and what would make Sussed more useful for your students. Genuinely.

I’ve found a bug or something is broken.
Email us with what happened, what you expected, and (if possible) the device and browser you were using. We fix issues quickly.

I have feedback or a feature suggestion.
Always welcome. You can use the Feedback tab inside the app, or email directly. Real feedback shapes what gets built next.
