Invalid emails hinder your marketing performance

Collecting incorrect, temporary, or non-existent email addresses is a major issue for any business. These errors lead to high bounce rates, damaged sender reputation, and wasted marketing resources.

Main negative impacts:

  • High bounce rates: Every email sent to a non-existent address hurts your credibility with receiving servers.
  • Damaged sender reputation: Poor list hygiene risks getting you flagged as spam, blocking your legitimate communications.
  • Wasted marketing budget: You pay to send messages to contacts who will never receive your offers.

With Swiftask and MailboxValidator, every email entry is verified instantly. Automation rejects invalid addresses at the source, ensuring a clean and qualitative database.

BEFORE / AFTER

What changes with Swiftask

Without automated validation

A lead enters an incorrect address in your form. The email is added to your database. Your next campaign suffers a bounce, your deliverability score drops, and you waste time manually cleaning your lists.

With Swiftask + MailboxValidator

The lead enters their email. Swiftask queries MailboxValidator in milliseconds. If the address is invalid, an error displays immediately. Only verified emails enter your CRM.

How to set up real-time validation in 4 steps

STEP 1 : Configure your MailboxValidator API key

Enter your MailboxValidator credentials in your Swiftask workspace to establish a secure connection.

STEP 2 : Define collection points

Select the forms or CRM tools you want to protect with automatic validation.

STEP 3 : Set filtering rules

Choose your risk tolerance threshold: block disposable addresses, non-existent domains, or malformed emails.

STEP 4 : Activate data flow

Validation is live. Every new lead is automatically filtered before any further processing.

Advanced validation features

Swiftask analyzes the format, domain, and receiving server validity for every email address submitted.
