What delivery boost does
A delivery boost shortens waiting time for a letter when you want a slightly faster arrival—while keeping the overall slow-mail spirit.
When boosts make sense
Use them for time-sensitive kindness (birthday letters) or when a conversation needs a gentler nudge—not for every message.
How to get free boosts
Watch for daily/weekly activities, events, and stamp-related rewards. Free boosts reward consistent writing more than rushing.
Keep the slow rhythm
SlowInk is still about thoughtful letters. Boosts are optional tools, not a replacement for waiting and anticipation.
FAQ
Do boosts remove the slow-mail feeling?
Used sparingly, no. They adjust timing for special moments while the app remains letter-first.
