The character limit for Custom Instructions in Brand Config has been raised from 1,000 to 2,500 characters, so you can include your full brand brief without trimming

What's Changing

Before: Custom Instructions in Brand Config were capped at ~1,000 characters. If you had a detailed brand brief — voice guidelines, product rules, formatting preferences, do's and don'ts — you had to trim it down or maintain a separate document and manually shorten for Backstroke. The generation pipeline only saw a fraction of your brand guidance, which meant emails wouldn't consistently follow all your rules.

After: The limit is now 2,500 characters. You can paste or write a full brand brief in one place — voice, tone, product rules, formatting notes — without arbitrary trimming. The entire brief is passed to the generation pipeline, so emails better match your brand guidelines. No more maintaining a separate shortened version or pruning on every edit.
