Control your risks with catch-all email analysis

Swiftask automatically evaluates the reliability of catch-all addresses. Protect your sender reputation by identifying threats before every campaign.

Result:

Drastically reduce bounce rates and secure your email marketing efforts.

The hidden dangers of catch-all addresses

Servers configured in 'catch-all' mode accept all emails, making traditional verification impossible. Sending messages to these addresses without prior analysis exposes your domain to major risks.

Main negative impacts:

  • Reputation degradation: A high bounce rate, even partial, signals to ISPs that your acquisition methods are questionable, leading to domain blocking.
  • Loss of marketing efficiency: Spending budget and time soliciting non-existent or toxic addresses mechanically reduces your overall ROI.
  • Data opacity: Without an analysis tool, you are flying blind, unable to distinguish a valid address from a spam trap.

Swiftask features an intelligent analyzer that cross-references behavioral data to assign a risk score to each catch-all address, allowing you to make informed decisions.

BEFORE / AFTER

What changes with Swiftask

Without Swiftask

You import a raw list into your email tool. Catch-all addresses are sent to blindly. Your bounce rate climbs, ISPs blacklist your IP, and your legitimate emails end up in spam folders.

With Swiftask + Catch-all Verifier

Before sending, Swiftask scans your lists. High-risk addresses are isolated and flagged. You clean your database in real time, ensuring optimal deliverability.

Secure your sends in 4 simple steps

STEP 1 : Integrate your lists into Swiftask

Connect your data sources or import your email lists directly into the secure Swiftask interface.

STEP 2 : Configure the catch-all analyzer

Activate the advanced verification module. The AI immediately begins analyzing response patterns from target servers.

STEP 3 : Get a risk score

Each address receives a reliability score based on thousands of behavioral signals, not just a simple server response.

STEP 4 : Act on your data

Automatically exclude dangerous addresses from your campaigns or segment them for specific treatment.

Intelligent verification capabilities

The agent examines DNS configurations, domain reception history, and bounce patterns specific to catch-all servers.

  • Target connector: The agent performs the right actions in catch-all verifier based on event context.
  • Automated actions: Dynamic risk score (0-100). Known spam trap detection. Automatic list cleaning. Clean segment exportation. Real-time alerts on high-risk domains.
  • Native governance: All analyses are stored in an audit report to justify your cleaning practices to your security teams.

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

Each Swiftask agent uses a dedicated identity (e.g. agent-catch-all-verifier@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.
