Great follow-up!
On average, after verifying your list through Mailcheck, you can expect deliverability rates to reach 95–98% assuming you're sending to our “Valid” emails only.
We help remove not just invalid addresses, but also temporary, risky, or role-based emails that can hurt your sender score. Plus, with our enrichment and social signals, you're not just reaching inboxes - you're reaching real people. 📬✨
Of course, overall deliverability also depends on your email content, sender domain, and sending practices but our system does the heavy lifting on the hygiene side.

Sera, with all due respect, that's not how email deliverability works. Bouncebacks are just one factor. If DMARC, DKIM, SPF, MTA-STS, and BIMI aren't properly configured, if excessive cold emails are sent, campaigns are sent with spam words or static messages, and the domain reputation is low, a sender would be lucky to get 25% deliverability.
At Mailcheck, we focus on the data quality side of the equation: cleaning invalid, temporary, risky, and role-based emails, while also enriching contacts with social and behavioral signals. This gives our users a stronger foundation, especially when sending to "Valid" emails only.
That said, as you pointed out, strong deliverability also depends heavily on technical setup (DMARC, SPF, DKIM, etc.)
