B2C email lists may decay slower than B2B lists, but that doesn’t mean you can neglect them. Unlike professionals who frequently change jobs in B2B scenarios, B2C contacts often use personal email addresses they’ve had for years, making them relatively more stable.
How Often To Verify Email Lists - (Best Practices + Case Study)
However, issues like hard bounces, spam complaints, and inactive subscribers can still sneak in over time if the list isn’t monitored.
Here’s a quick guide for keeping your B2C list healthy:
For Single Opt-In Lists:
Verify every 25-30 days for weekly or frequent campaigns.
For campaigns spaced 2 months apart or more, verify before every campaign.
For Double Opt-In Lists:
Once every quarter is sufficient if usage of this application campaigns are sent weekly or regularly.
Quarterly check for monthly or less frequent campaigns.
Why is this necessary?
B2C subscribers often lose interest, abandon inboxes, or switch email providers, leading to inactive accounts. Many sign up with temporary or fake emails just to snag discounts or freebies.
Coupled with high expectations—where subscribers may unsubscribe or mark emails as spam if content feels irrelevant—consistent verification ensures your campaigns stay effective and reach engaged recipients.
