Push Only Verified Clay Rows to Instantly or Smartlead

To push only verified rows from Clay to a sequencer, give the push column a run condition: only run if the verification action is send. Only a confirmed mailbox ("Mailbox exists") gets that action. The verification column is Clay's HTTP API enrichment calling SimpleVerifier with your own key; it is not a native Clay action. The request is on the Clay integration page. This post is about the push, and it applies to any sequencer, including Instantly and Smartlead.

Step 1: verify before the push column

Order the table: find, verify, then push. Our Clay verification guide builds the column and sets the rate limit. Map action and reason to their own columns.

Step 2: gate the push

Add the run condition to whichever column sends rows out, whether that is a sequencer action, a webhook or an export:

Condition	Result
action is send	Row is pushed to the main campaign
Anything else	Row stays in the table

A filtered view alone is not a gate, because a column set to run on every row still acts on rows the view hides. Put the condition on the push column itself.

Step 3: give risky rows their own route

action	Reasons	Route
send_with_care	Accepts all addresses, Role-based address	Second campaign, small batches
retry_later	Server would not confirm	Re-run, see retry rows
do_not_send	Mailbox not found, Disposable address	Not pushed

Use a different campaign, and separate sending inboxes if you can, for the care lane. A bad segment then cannot drag down the inboxes carrying your confirmed list. Our guides to Instantly bounce rate and Smartlead bounce rate explain why sequencers pause on bounces.

Step 4: add a suppression step

Rows marked do_not_send should join a suppression list so a later import does not bring them back. See building a cold email suppression list.

If you export instead of pushing

Download the filtered view as CSV and upload it to the sequencer. For the file route, see exporting a Clay table to a clean list, cleaning an Instantly or Smartlead list and the Instantly CSV upload guide.

What this cannot do

• It does not connect to your sequencer for you. The push column and its credentials are yours to set up in Clay.
• Verified is a statement about the mailbox on the check date, not about the person's interest.
• A catch-all domain cannot be confirmed by any check and is never returned as valid.
• Sending cold email still has rules where your recipients are.
