About
This skill automates a weekly manual review process for contacts with 3+ email bounces, helping developers decide whether to delete or attempt recovery for each contact. It prevents over-suppression by ensuring a human reviews auto-flagged data before permanent action. The process includes a scripted pre-filtering stage using the HubSpot API to prepare the review list.

Review Bounced Contacts
A weekly manual review process for contacts flagged with 3+ bounces. The bounce monitoring workflow auto-suppresses these contacts, but a human should decide whether to permanently delete or attempt recovery.
Prerequisites
- Bounce monitoring workflow active (run
/bounce-monitoring-workflowfirst) email_health_flagcustom property exists on contacts- HubSpot API token in
.env(for scripted pre-filtering)
Step-by-Step Instructions
Stage 1: Before — Pull the Review List
Use the HubSpot API to search for contacts where email_health_flag is set:
from hubspot import HubSpot
from hubspot.crm.contacts import PublicObjectSearchRequest
api_client = HubSpot(access_token=os.getenv("HUBSPOT_API_TOKEN"))
search = PublicObjectSearchRequest(
filter_groups=[{
"filters": [{
"propertyName": "email_health_flag",
"operator": "EQ",
"value": "true"
}]
}],
properties=["email", "firstname", "lastname", "company",
"hs_email_bounce", "hs_email_hard_bounce_reason_enum",
"lifecyclestage", "hubspot_owner_id"]
)
results = api_client.crm.contacts.search_api.do_search(search)
Export results to a CSV for review.
Stage 2: Execute — Review Each Contact
For each flagged contact, check:
- Is the email domain active? Run a quick MX record lookup or visit the domain.
- Is this a known customer or high-value contact? Check lifecycle stage and deal history.
- What is the bounce reason? Hard bounce (invalid mailbox) vs. soft bounce (mailbox full, temporary error).
Decision matrix:
| Domain active? | High value? | Bounce type | Action |
|---|---|---|---|
| No | Any | Any | Delete |
| Yes | No | Hard | Delete |
| Yes | No | Soft | Keep suppressed, recheck next quarter |
| Yes | Yes | Hard | Attempt to find updated email |
| Yes | Yes | Soft | Keep suppressed, monitor |
Stage 3: After — Execute Decisions
- Delete contacts marked for deletion via the HubSpot UI or API batch delete.
- Clear the
email_health_flagon all reviewed contacts. - Log the review results (deleted count, kept count, recovery attempts) for the quarterly report.
Stage 4: Rollback
- Deleted contacts can be restored from HubSpot's recycling bin within 90 days.
- Contacts kept as suppressed can be restored to marketing status via a workflow or manual update in the UI.
Frequency
Run weekly, ideally Monday morning. Should take 5-15 minutes depending on volume. If volume exceeds 50 contacts per week, investigate the root cause (bad list source, form spam, etc.).
