# outreach agent's follow-ups ignored the candidate's timezone - every send fired at 9am UTC

## TL;DR

The agent scheduled every follow-up for 9am UTC, which is 2am in Los Angeles and 6pm in Tokyo. Localize send times to the candidate's timezone (from their location or phone), and default to mid-morning local. Batch-and-blast at one UTC time is bot behavior that spam filters notice.

outreach agent's follow-ups ignored candidate timezone - all sends at 9am UTC
```

## Steps

1. Confirm the pattern: check send timestamps against candidate timezones.
   Expected: Every send lands at 9am UTC regardless of location.

2. Resolve each candidate's timezone from their location, area code, or profile data.
   Expected: Most candidates get a confident zone.

3. Reschedule the sequences to mid-morning local time per candidate.
   Expected: Sends spread across the day by zone.

4. Handle unknowns gracefully: default to a neutral window (mid-morning UTC) and note the assumption.
   Expected: No candidate gets a 3am email.

5. Monitor reply rates by local send hour to tune the window.
   Expected: The data confirms the fix.

## When to use

- follow-ups arrive at odd local hours
- all sends share one UTC timestamp
- reply rates are mysteriously low

## When not to use

- the audience is all in one timezone (then 9am UTC may be fine)
- the sends are time-sensitive announcements (send immediately, note the tradeoff)
- timezone data is unavailable and unreliable (pick the least-bad default)

## Tool compatibility

- any outreach sequencing agent
- timezone resolution

## Variant phrasings

- "follow-ups ignored timezone"
- "all sends 9am UTC"
- "outreach wrong local time"

## Why it happens

Engagement follows local rhythms: a 9am-local email gets opened, a 3am-local email gets buried or flagged. The agent optimized for its own scheduling simplicity and ignored the recipient's clock. Spam filters also notice synchronized bursts, so the single-UTC-time pattern hurts deliverability twice.

## Edge cases

- daylight-saving changes shift the mapping; recompute zones, do not cache them forever
- candidate location data can be stale; prefer the phone area code over the profile city
- some candidates travel; the last-known zone beats no zone
