Does Keap verify email addresses?

Keap validates email format when contacts are added but does not verify whether addresses exist or can receive mail. Truelist provides full SMTP-level verification.

I have been using Keap for years. How bad is my data likely to be?

Email databases lose roughly 25% validity per year. If you have not cleaned your Keap list recently, 30-50% of older contacts may be invalid depending on when they were added.

Can I tag invalid contacts instead of deleting them?

Yes. After verification, you can apply a tag like "Invalid Email" in Keap and exclude that tag from all campaigns and automations instead of deleting records.

Will this help with Keap's email sending limits?

Yes. Keap monitors bounce rates and may restrict sending for accounts with high bounces. Cleaning your list keeps you in good standing with Keap's sending policies.

Keap (formerly Infusionsoft) is a CRM and marketing automation platform designed for small businesses, combining contact management, email marketing, and e-commerce.

Why verify your Keap email list

Keap databases accumulate contacts over years from landing pages, checkout flows, manual entry, and imported lists. Older contacts decay as people change email providers, abandon addresses, or leave companies. Without verification, your Keap automations send to an increasingly invalid audience, hurting deliverability and wasting automation capacity.

inbox Rescue Automation Performance: Keap automations trigger emails to every matching contact. Invalid emails waste sends and drag down campaign metrics.
savings Reduce Keap Costs: Keap pricing scales with contact count. Purging invalid emails can meaningfully reduce your monthly bill.
shield Prevent Deliverability Crises: Small business domains are especially vulnerable to blacklisting. Clean lists protect your sender reputation.
analytics Accurate Sales Pipeline: Contacts with invalid emails cannot be nurtured. Removing them gives you a realistic view of your actual pipeline.
