Lower your email bounce rate by automating Neverbounce

Swiftask integrates Neverbounce into your data flows. Automatically clean your lists before every campaign to ensure optimal deliverability.

Result:

Protect your domain reputation and ensure your emails actually reach your prospects' inboxes.

High bounce rates hurt your sender reputation

Sending campaigns to invalid addresses is the fastest way to land in spam. Manual list cleaning is tedious, often forgotten, and doesn't allow for enough reactivity when acquiring new leads.

Main negative impacts:

  • Degraded deliverability: Email providers (Gmail, Outlook) penalize senders with high bounce rates, blocking your future communications.
  • Wasted operational time: Manually managing email lists before every send consumes valuable resources that should be dedicated to strategy.
  • Unnecessary marketing costs: You pay to send emails to addresses that no longer exist or are invalid, wasting your budget and effort.

Swiftask connects Neverbounce to your CRM or marketing platforms. Every new email is verified automatically, ensuring only valid addresses enter your mailing lists.

BEFORE / AFTER

What changes with Swiftask

Before automation

You export your contact lists, manually upload them to Neverbounce, wait for the result, then re-import the valid addresses into your sending tool. It's a repetitive task prone to errors and oversights.

With Swiftask + Neverbounce

As soon as a new contact is added or updated in your system, Swiftask automatically sends the email to Neverbounce for verification. The status is updated in real-time: your list is always clean, with no action required from you.

Setting up your cleaning workflow in 4 steps

STEP 1 : Connect your tools to Swiftask

Link your CRM or database to Swiftask. No complex development is required.

STEP 2 : Integrate Neverbounce as a skill

Add Neverbounce to your Swiftask agent via a simple, secure API key.

STEP 3 : Define trigger rules

Configure the agent to automatically verify every new email added or when a contact is modified.

STEP 4 : Automate updates

The agent automatically marks the contact as 'valid' or 'invalid' in your CRM based on the Neverbounce result.

What your email cleaning agent can do

The agent continuously analyzes incoming new contacts, performs API calls to Neverbounce, and orchestrates data updates in your CRM.

  • Target connector: The agent performs the right actions in neverbounce based on event context.
  • Automated actions: Instant email verification. Automatic filtering of risky addresses. CRM status updates. Complete activity reports for verifications performed.
  • Native governance: Swiftask provides full logging of every verification for precise tracking of your database quality.

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

Each Swiftask agent uses a dedicated identity (e.g. agent-neverbounce@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.
