What it does

Verifyre and SendGrid, together.

Reads your Marketing Campaigns lists

Verifyre lists every list in your SendGrid account and streams its contacts page by page, so even a list of hundreds of thousands never has to be exported.

Verifies with a real handshake

Each address goes through syntax, DNS, disposable and role checks and an SMTP conversation with its own mail server, with per-domain politeness so no provider is hammered.

Writes the verdict back

Undeliverable contacts are handled inside SendGrid, after you have reviewed the results.

Setup guide

Set up SendGrid in 4 steps.

You will need: a Verifyre account (free) and your SendGrid api key.

  1. Create an API key in SendGrid

    In SendGrid go to Settings, then API Keys (restricted access: Marketing and Suppressions) and create a key named Verifyre. Copy it; you will paste it once and never see it again on our side (it is encrypted with AES-256-GCM at rest).

  2. Connect it in Verifyre

    Sign in, open Integrations, choose SendGrid and paste the key. Verifyre tests it immediately and shows the account it belongs to. A wrong key says exactly what SendGrid answered.

  3. Verify a list

    Pick a list from the list, confirm the credit estimate (one credit per unique address, duplicates are free) and start. Watch the counts fill in live; you get an email when the job is done.

  4. Push results back

    From the finished list, choose the write-back action. Verifyre applies it only to undeliverable contacts by default; risky contacts (catch-all domains, role accounts) are left for you to decide on with the exported CSV.

Where exactly the api key lives

In SendGrid open Settings, then API Keys, then Create API Key. Choose Restricted Access and allow Marketing (full) and Suppressions (full), then copy the key (it starts with SG.).

Write-back

What gets written back to SendGrid.

Verification only reads. Writing results back is a separate step you trigger after reviewing the counts, and nothing is ever deleted without your say-so.

  • Undeliverable addresses added to SendGrid's global unsubscribe group, so neither Marketing Campaigns nor your transactional sends ever hit them again.

SendGrid FAQ

SendGrid questions

Visit the help centre
Does Verifyre store my SendGrid contacts?
Contacts are held only for the duration of the job and the result rows you can download; the credentials are encrypted and can be disconnected at any time, which deletes them.
How many credits does a sync use?
One credit per unique, well-formed address in the list. Duplicates, syntax failures and addresses verified in the last 24 hours are free.
Will it unsubscribe contacts without asking?
No. Verification only reads. Writing back is a separate step you trigger from the finished list, and you choose which action to apply.
My SendGrid list is very large. Is there a faster way?
SendGrid's contact search returns 50 contacts per page, so lists over roughly 50,000 are quicker to export as CSV from SendGrid and upload to Verifyre directly. The write-back works the same either way.
