Disposable emails damage your marketing performance
The use of temporary email addresses by your leads pollutes your database. These addresses increase bounce rates, degrade your reputation with ISPs, and skew your performance analytics.
Main negative impacts:
High bounce rates
Disposable emails expire quickly, leading to hard bounces that penalize your deliverability.
Wasted marketing budget
You pay for inactive contacts who will never open your emails, wasting your CRM budget.
Corrupted data
Your engagement statistics are biased by low-value leads, preventing accurate segmentation.
Swiftask automates the filtering process: as soon as a new email is captured, the agent queries the Abstract API. If the address is flagged as disposable, the agent blocks or removes it instantly.
BEFORE / AFTER
What changes with Swiftask
Without Swiftask
A user signs up with a temporary address. Your CRM records it. During your next campaign, 20% of your emails bounce. You have to clean your lists manually, a repetitive and time-consuming task.
With Swiftask + Abstract API
Upon form submission, the Swiftask agent verifies the email via Abstract. If it's a disposable email, it is automatically rejected before entering your database. Your list remains clean and high-performing.
4 steps to automate your email list cleaning
1
STEP 1 : Connect Abstract API to Swiftask
Add your Abstract API key to your Swiftask account settings to enable real-time verification.
2
STEP 2 : Define the trigger
Configure the agent to run whenever a new entry is created in your CRM or a form is submitted via webhook.
3
STEP 3 : Configure the filtering action
Set the rule: if Abstract returns 'disposable: true', the agent deletes the record or moves it to a rejection list.
4
STEP 4 : Activate and monitor
The agent works in the background. You receive periodic reports on blocked registration attempts.
