Email Remediation for SaaS Churn Prevention

For subscription SaaS businesses, proactively identifying and correcting invalid customer emails is vital for preventing involuntary churn and maintaining clear communication channels. Verifyr helps you retain valuable subscribers.

The problem

Involuntary churn is a silent killer for SaaS companies, often triggered by failed payments where customers are unreachable due to outdated or incorrect email addresses. Critical notifications about expiring cards, payment retries, or subscription issues bounce back, leaving customers unaware and ultimately leading to subscription cancellations. This direct loss of revenue is entirely preventable with better communication.

Over time, customer email lists naturally degrade due to job changes, domain expirations, or simple typos made during initial signup. Relying on an unvalidated customer email database means your customer success and billing teams are working with faulty data, leading to wasted outreach efforts and missed opportunities to re-engage at-risk customers. Proactive remediation is key to a healthy subscription base.

How Verifyr solves it

1
Batch validate your existing customer database to identify and flag invalid or outdated email addresses for remediation.
2
Integrate Verifyr into your CRM or billing system to re-validate emails at critical touchpoints, like payment updates.
3
Ensure all churn-prevention communications, such as payment failure alerts, reach your customers effectively.

Concrete example


# Python script for batch email remediation
import csv
import requests

api_key = "YOUR_VERIFYR_API_KEY"
emails_to_remediate = []
with open('customer_emails.csv', 'r') as f:
    reader = csv.reader(f)
    for row in reader:
        email = row[0]
        response = requests.get(f"https://api.verifyrhq.com/v1/validate?email={email}&api_key={api_key}")
        data = response.json()
        if not data.get("valid") or data.get("disposable"):
            emails_to_remediate.append((email, data.get("reason", "invalid")))
