Work out the amount
Pick the occasion, the relationship, the details — down to the venue (hotel, banquet hall or restaurant) and the region — and get an honest range rather than a number pretending to be precise. Every figure links to its source, and where sources disagree the range widens instead of being averaged into false precision. The north tends to run one tier higher. Going in with colleagues? Turn on the pooled envelope and it shows "3 people sharing one envelope," split into what you actually gave. Once you have a figure, add a line of envelope phrases and share the result to the group chat.
