Sanitize your legacy email databases with ZeroBounce

Swiftask links your dormant email lists to ZeroBounce for automatic cleaning. Remove bounce risks and protect your sender reputation.

Result:

Restore your data quality without technical intervention. Boost your deliverability rates instantly.

Why legacy email lists are hurting your business

Accumulating contacts over years creates massive technical debt. Emails become inactive, domains close, and disposable addresses pile up. Sending campaigns to these degraded lists destroys your IP reputation and causes deliverability rates to plummet.

Main negative impacts:

  • High bounce rates: Invalid emails cause mass bounces, alerting ISPs that your list is not properly qualified.
  • Damaged sender reputation: Poor list hygiene drives your legitimate emails straight into the spam folder.
  • Wasted CRM costs: You pay to store and manage thousands of inactive contacts that will never convert.

Swiftask automates your data lifecycle. By integrating ZeroBounce, your legacy lists are validated and cleaned in the background, without manual CSV exports or imports.

BEFORE / AFTER

What changes with Swiftask

Without Swiftask

You identify a two-year-old database. You export the contacts, manually import them into a validation tool, download the report, then clean your CRM. The process takes days and is already outdated by the time it finishes.

With Swiftask + ZeroBounce

Swiftask monitors your data segments. As soon as a contact is identified as legacy, it's sent to ZeroBounce for validation. Invalid addresses are marked or deleted automatically in your CRM in real time.

Clean your data in 4 simple steps

STEP 1 : Connect your data sources

Set up Swiftask to access lists in your CRM or SQL database.

STEP 2 : Integrate ZeroBounce API

Add your ZeroBounce API key to Swiftask to enable real-time validation.

STEP 3 : Define your cleaning rules

Choose which types of addresses to delete or update (invalid, catch-all, disposable).

STEP 4 : Launch automation

The agent processes your legacy lists continuously. You receive reports on data quality.

Advanced cleaning capabilities

The agent assesses each address's health via ZeroBounce by analyzing syntax, domain status, and real-world account activity.

  • Target connector: The agent performs the right actions in zerobounce based on event context.
  • Automated actions: Real-time validation of new entries. Scheduled batch cleaning of existing databases. Automatic CRM field updates. Removal of high-risk addresses.
  • Native governance: All cleaning actions are logged in Swiftask to give you full visibility on your data quality evolution.

Each action is contextualized and executed automatically at the right time.

Each Swiftask agent uses a dedicated identity (e.g. agent-zerobounce@swiftask.ai ). You keep full visibility on every action and every sent message.

Key takeaway: The agent automates repetitive decisions and leaves high-value actions to your teams.
