Swiftask integrates MailboxValidator to clean your lists in real-time. Automatically eliminate risky addresses before every campaign.
Result:
Maintain high deliverability and prevent your domains from being blocked by ISPs.
The risks of an unverified email list
Sending campaigns to invalid or risky addresses is the fastest way to degrade your reputation. Email servers detect these errors, increase your bounce rate, and eventually mark your emails as spam.
Main negative impacts:
Swiftask automates filtering via MailboxValidator. Each new address is validated instantly, ensuring only qualified prospects receive your communications.
BEFORE / AFTER
What changes with Swiftask
Manual bounce management
You send a campaign to an unverified list. Hundreds of messages bounce. Your marketing team has to manually clean the files afterward. The damage is done: your reputation is tarnished.
Proactive protection with Swiftask
As soon as a contact is added, Swiftask queries MailboxValidator. Invalid addresses are automatically excluded. Your campaign is sent only to healthy addresses, protecting your domain.
Secure your sends in 4 steps
STEP 1 : Connect MailboxValidator
Integrate your MailboxValidator API key into Swiftask via our secure connector management interface.
STEP 2 : Define your workflow
Create a Swiftask agent that triggers verification when a prospect is added to your CRM or database.
STEP 3 : Apply filtering rules
Configure the agent to reject or flag 'risky' or 'invalid' addresses returned by the API.
STEP 4 : Automate cleaning
The agent cleans your lists automatically in real-time without any human intervention.
Intelligent verification capabilities
The agent evaluates the validity score, syntax, domain existence, and the presence of 'catch-all' or 'disposable emails' for each contact.
Each action is contextualized and executed automatically at the right time.
Each Swiftask agent uses a dedicated identity (e.g. agent-mailboxvalidator@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.
