How to integrate Truelist with Drip

Truelist has a direct integration with Drip that validates your subscriber list and writes the validation result back to each subscriber as a tag. This guide walks you through setup and day-to-day management.

How the integration works

When you connect Drip, Truelist fetches all subscribers from your account and runs each email address through its full validation pipeline. Once validation is complete, Truelist applies one of the following tags to each subscriber in Drip:

  • truelist-valid — The email address is valid and safe to send to.
  • truelist-risky — The email address may be valid but carries some risk (e.g. disposable or role address).
  • truelist-invalid — The email address is invalid and should not be sent to.
  • truelist-unknown — Truelist could not determine the validity of the email address.

You can use these tags in Drip to build segments, suppress invalid addresses from campaigns and workflows, and keep your subscriber list clean over time.

After setup, Truelist can validate your list automatically on a weekly basis, or you can trigger a sync manually at any time.

Before you begin

You will need a Drip API key and your Drip account ID.

Finding your API key

  1. Log in to your Drip account.
  2. Click your profile icon (top-right) → User Settings.
  3. Go to the API tab.
  4. Copy your API key.

Finding your account ID

Your account ID appears in the URL when you are logged in to Drip:

https://www.getdrip.com/ACCOUNT_ID/dashboard

Copy the number between getdrip.com/ and /dashboard.

Step-by-Step Setup

  1. Go to Settings → Integrations in your Truelist account.
  2. Find the Drip card under Available integrations and click Set up.

  1. You will be taken to the Drip settings page.
  2. Click Sync now to kick off your first validation run.

Managing the Integration

Drip integration settings page

Sync settings

Use the Status dropdown to control how syncing works:

  • Enabled, sync automatically — Truelist will validate your subscriber list on a weekly basis without any manual action.
  • Enabled, but sync manually — Syncing is enabled but will only run when you click Sync now.
  • Disabled — Syncing is paused. No new validations will run until you re-enable it.

Syncing now

Click the Sync now button to immediately kick off a validation of your Drip subscribers. Truelist will only validate email addresses that have not been validated recently. Existing results are cached and re-used based on your revalidation settings.

Drip sync in progress on the Verify a List page

Note: When a Drip sync is in progress, the batch will appear in your Verified Lists section. The CSV download will be empty — results are written directly back to your subscribers as tags in Drip, not stored as a downloadable list.

Deleting the integration

Click the Delete Drip integration button to remove the connection entirely. This stops all syncing. It will not delete any data in Drip or Truelist — your existing tags and validation history are preserved. You can reconnect the integration at any time.

Using validation results in Drip

Once a sync completes, each subscriber will have one or more Truelist tags applied. Here are some common ways to put them to use.

Suppress invalid addresses from campaigns

Before sending a campaign, add a filter rule to exclude subscribers tagged truelist-invalid. This prevents sending to bad addresses that would raise your bounce rate.

Build a clean segment for high-value sends

Create a segment in Drip with the condition tag is truelist-valid. Use this segment for re-engagement campaigns or any send where deliverability is critical.

To create a segment, go to People → Segments and click Go to the segment builder.

Drip People Segments page

Add a filter for Tags → has this tag → truelist-valid and click Save segment.

Filtering Drip subscribers by truelist-valid tag

Quarantine risky addresses

Create a separate segment for subscribers tagged truelist-risky. You can choose to suppress these from regular sends while continuing to email validated addresses, or review them manually before deciding.

Remove unknowns after repeated syncs

If a subscriber is still tagged truelist-unknown after two or three sync cycles, consider suppressing or removing them. A persistent unknown result often indicates a problematic address.

Frequently Asked Questions

How often will my Drip list sync automatically?

When set to automatic, Truelist will sync your subscribers once per week.

Will Truelist re-validate subscribers it has already checked?

Yes. Truelist re-validates existing subscribers according to the revalidation period configured in your validation settings. The default is 60 days.

Can I validate my list on demand?

Yes. Click Sync now on the Drip integration settings page to trigger an immediate validation run.

Does Truelist validate all subscribers or just new ones?

Each sync fetches all subscribers from your Drip account. Truelist skips addresses that were validated recently (within your revalidation window) and only runs validation on new or stale addresses, so credits are not wasted on re-checking recent results.

Will the integration change any subscriber data other than tags?

Truelist only applies the truelist-valid, truelist-risky, truelist-invalid, and truelist-unknown tags. It does not modify any other subscriber fields, delete subscribers, or unsubscribe contacts.

What happens if my Drip credentials change?

If Truelist cannot authenticate with Drip during a sync, the integration will be automatically disabled and you will receive an email notification. Go to Settings → Integrations → Drip and re-enter your credentials to reconnect.
