Add honest email validation to any Pabbly Connect workflow
Validate an address inside any Pabbly Connect workflow using the built-in API module. Mail7 returns Valid, Not Valid or Unknown, so you filter out only confirmed-invalid addresses and keep the real ones moving.
No marketplace app needed - set it up today with Pabbly's built-in API module.
Validate with the API by Pabbly module
Pabbly Connect does not need a dedicated Mail7 app. You call the Mail7 API straight from the built-in API by Pabbly action, so this works today on any account with no marketplace approval. One action step scores each address as it flows through your workflow.
Three outcomes to branch on: Valid, Not Valid, Unknown
The step returns a three-way status you can branch on with a Filter or Router, instead of a binary verdict that quietly drops real people:
Confirmed mailbox. Continue the workflow.
Confirmed invalid. Route it out or tag it.
Unconfirmed. Keep it moving, do not treat as invalid.
Set up the validation step
-
1
Add an API by Pabbly action
After your trigger, add an action step and pick API by Pabbly, event Execute API Request.
-
2
Set method and URL
Method POST, endpoint
https://mail7.net/api/validate-single. -
3
Add headers and JSON body
Header
Content-Type: application/json(addX-API-Keyfor volume); body{ "email": "{{trigger.email}}" }. -
4
Branch on status
Add a Filter or Router on the returned status field: route out only Not Valid, keep Valid and Unknown.
Branch on the result, keep Unknown
A safe default is one Filter with the condition status is not equal to Not Valid, so everything except confirmed-invalid continues. Unknown covers catch-all domains, greylisting and servers that block SMTP checks, none of which mean the address is fake, so keep those.
Free single checks, paid plans for volume
Single checks are free and need no account, so you can preview the exact result the step returns. Add a Mail7 API key to lift the anonymous rate limit for high-volume workflows, and you are only charged for definite Valid and Not Valid results. Unknown checks are always free.

Frequently asked questions
Do I need a Mail7 app in Pabbly?
No. You use the built-in API by Pabbly module to call the Mail7 endpoint directly, so there is nothing to install.
What does the step return?
A three-way status (Valid, Not Valid, Unknown) plus per-check fields, all mappable in later steps.
Should I drop Unknown addresses?
No. Unknown means unconfirmed, not fake; branch out only Not Valid.
Do I need an API key?
Not for single checks. Add one to lift the anonymous rate limit for high-volume workflows.
Are Unknown checks billed?
No, Unknown results are always free.
