Pre-send outreach list verification

Every Thursday, verify your outreach list with Hunter before the next send — deliverable, risky, and undeliverable addresses bucketed, with the ones to remove called out so your sender reputation stays clean.

Works with
The instructions
Every Thursday, verify my outreach list with Hunter and email me a pre-send report. Verification
only — never send email to any address.

1. Take the list of addresses I keep for this routine (paste them into the instructions, or point
   at the source the connection can read). Verify each one with Hunter's email verifier. Cap the
   run at 100 addresses so it stays within my credit budget; if the list is longer, verify the
   first 100 and say how many were left unchecked.

2. Bucket the results: deliverable, risky, and undeliverable. Treat accept-all domains, low
   verification scores, disposable addresses, and obvious role addresses (info@, sales@) as
   risky. Give each bucket as a count and a percentage.

3. List every undeliverable address so I can remove it before the send, and every risky one with
   the reason (accept-all, role-based, low score) so I can decide case by case.

Lead with a one-line headline: how many addresses were checked and what share are safe to send to.
Keep it skimmable — biggest problems first. If an address can't be verified, put it in risky and
say why rather than guessing.
What a run emails you
Pre-send verification — Thu 25 Jun 2026

Checked 100 addresses — 81% safe to send. 7 should be removed before Monday's campaign.

Buckets
• Deliverable — 81 (81%)
• Risky — 12 (12%)
• Undeliverable — 7 (7%)

Remove before sending (7)
• dana@oldcorp.com — mailbox not found
• j.reyes@northwind.io — domain no longer accepts mail
• …5 more

Review case by case (12)
• 8 accept-all domains (scores 55–68) — deliverability can't be confirmed
• 3 role-based (info@, sales@) — high complaint risk for cold outreach
• 1 disposable address

One bad send can cost weeks of sender reputation. This routine puts a verification gate in front of your outreach cadence: every Thursday it runs your list through Hunter's email verifier and tells you exactly which addresses to pull before the next campaign goes out.

How it works

  • Attach your Hunter connection and keep your outreach list where the routine can read it —
  • pasted into the instructions or in a connected source.
  • Every address is verified and bucketed as deliverable, risky, or undeliverable, with the
  • reason attached — a dead mailbox reads differently than an accept-all domain.
  • The run is capped at 100 addresses, so verifications spend a predictable amount of your Hunter
  • credits, and it tells you when a longer list was only partially checked. Keep **"Email me the
  • result"** on to get the report before each send.

Make it yours

  • Match the cadence to your sending schedule — Thursday works for a Monday campaign; move it to
  • daily during a big push.
  • Set your own policy for risky addresses: some senders drop accept-all domains outright, others
  • keep them on a low-volume track — tell the routine and it'll bucket accordingly.
  • Pair it with the source of truth for your list (a sheet, your CRM) so additions get verified
  • automatically instead of by hand.

Your connection stays yours: your API key is encrypted at rest, and this routine's instructions are verification-only — they tell the agent to read deliverability results, never to touch your Hunter campaigns or email your contacts.
