Get the list of affected accounts so you can reach out first.

To find which customers a bug affects, ask Maito in Slack with a description of the bug. It queries your database and analytics for matching accounts, picks out Enterprise and repeat cases and finds who hasn't contacted support. You get a list of accounts as a file, plus a draft heads-up email. ## How it's done today Support waits for customers to write in. ## What Maito does 1. Read the bug 2. Find accounts using the affected feature 3. Draft a heads-up email ## Example **Sam** (1:15 PM): which customers are hit by the export bug? ENG-2291 says anything over 10,000 rows. **Maito** (1:21 PM): 37 accounts ran an export over 10,000 rows since release 2.41 on Oct 14. BigQuery has the row counts, and PostHog shows 212 failed export events across them. • 9 are Enterprise, including Globex and Hooli. • 6 failed 5 or more times. **Catch:** only 11 of the 37 have written to support. The other 26 are still silently failing, and that includes Hooli. Attached: affected-accounts.csv and export-heads-up-draft.docx, a short note with a workaround (export in two date ranges). **Sam** (1:30 PM): make Gmail drafts for the 26 who haven't written. I'll check and send. **Maito** (1:36 PM): 26 drafts are in your Gmail, addressed to each account's admin. Nothing is sent. The 6 repeat failures are marked at the top of the list. ## How to set it up When you ask Find out which customers a bug affects Set up Nothing to set up.

Your agent sends you a link to sign in. ## What it won't do It finds accounts based on the conditions you describe. If the bug leaves no trace in your data, it can't count them. ## Questions ### Which data sources does it use? BigQuery or Supabase for the data, and Amplitude, Mixpanel or PostHog for events. ### Will it email the affected customers? No. It drafts the note and a person sends it. ### Does it find customers who never wrote in? Yes. Comparing the affected list with support contacts shows who is still failing silently. ## More customer support workflows - [Draft replies to tickets you've solved before When a question has been answered before, get a draft reply from that answer.
