Swiftask connects your workflows to the Abstract Email Verification API. Clean your contact lists in bulk and eliminate invalid addresses effortlessly.
Result:
Boost your deliverability rate and protect your sender domain reputation.
Outdated email lists hurt your performance
Sending campaigns to invalid or non-existent addresses degrades your sender reputation. Manual processing is slow and error-prone, while letting 'dead' contacts pile up costs you money in bounce rates.
Main negative impacts:
Swiftask automates your batch email processing. Whenever a new contact is added or on a schedule, your AI agent queries the Abstract API to validate your lists in real time.
BEFORE / AFTER
What changes with Swiftask
Without Swiftask
You manually export your CRM base, run a complex script or third-party tool, wait for results, and re-import cleaned data. This process is disconnected from your daily tools and rarely happens.
With Swiftask + Abstract API
As soon as a new list is ready, Swiftask automatically sends addresses to the Abstract API. Invalid addresses are flagged or removed instantly in your CRM. Your base stays clean, always.
4 steps to automate your email verification
STEP 1 : Configure your Swiftask agent
Create a dedicated data processing agent. Define the trigger: file import, CRM webhook, or weekly schedule.
STEP 2 : Connect the Abstract Email Verification API
Add your Abstract API key in Swiftask. The connection is secure and allows you to query the service for every contact.
STEP 3 : Define processing rules
Tell the agent what to do with invalid emails: delete the contact, update a 'status' field in your CRM, or send an alert.
STEP 4 : Run and monitor
Start the batch process. Swiftask manages API calls and provides a full report of verified emails.
Advanced verification capabilities
The agent analyzes the result returned by Abstract: syntax, domain existence, active mailbox, and detection of 'catch-all' or temporary addresses.
Each action is contextualized and executed automatically at the right time.
Each Swiftask agent uses a dedicated identity (e.g. agent-abstract---email-verification-api@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.
