Email is the most important part of SaaS growth. Every interaction, from onboarding sequences to product updates to marketing campaigns, depends on getting to the user's inbox.

But here's the problem that most teams don't know about: email lists don't last as long as they think they do.

According to the Data & Marketing Association, email databases lose 20–30% of their accuracy each year due to people changing jobs, domains expiring, and people signing up with fake email addresses.

For SaaS businesses that depend on CRM integrations and automated workflows, bad emails can quickly cause: 

• High bounce rates

• Sender's reputation is hurt

• Bad delivery

• Missed chances to make money

That's why it's so important to pick the best email verify tool.
