Email Validation

The Email Quality Crisis

Email lists decay at 22.5% per year according to HubSpot. That means nearly a quarter of your email database is invalid right now. You're sending to addresses that bounce, damaging your sender reputation, and wasting every dollar you spend on email marketing.

Bounce Rates Destroy Sender Reputation

ISPs watch your bounce rate. Above 2%, you start getting flagged. Above 5%, you're getting throttled. Above 10%, your entire domain may be blacklisted. Once your sender reputation tanks, even your valid emails start landing in spam. Recovery takes months.

Invalid Emails Waste Campaign Budget

Every email sent to an invalid address costs you money in platform fees and opportunity cost. If you're running 50,000-record campaigns with a 15% invalid rate, that's 7,500 wasted sends per campaign. Over a year of weekly campaigns, that's hundreds of thousands of wasted sends.

Catch‑All Domains Hide Problems

Some domains accept all incoming email regardless of whether the address exists. Your ESP shows them as 'delivered' but nobody reads them. Without catch-all detection, you think your list is clean when 10-15% of your 'delivered' emails hit dead ends.

Role Addresses and Spam Traps

info@, sales@, admin@ addresses don't belong in B2B outreach sequences. Neither do recycled spam traps set up by ISPs to catch senders with bad list hygiene. Both lower your deliverability and can get you blacklisted.

How Verum Handles Email Validation

We validate every email address in your database using SMTP-level verification, syntax checks, domain analysis, and spam trap detection. You get back a clean list with status codes on every address.

SMTP‑Level Verification

We connect to the recipient mail server to verify each address exists and can receive mail, without actually sending a message. This catches invalid addresses that syntax checks alone would miss.

For your team: Every email comes back with a status: valid, invalid, catch-all, disposable, or role-based. You decide which statuses to keep in your campaigns.

Catch‑All and Disposable Detection

We flag domains that accept all incoming email (catch-all) and addresses from temporary email services (disposable). These require different handling than verified or clearly invalid addresses.

Human QA on Everything

Bulk verification tools produce false negatives on some legitimate enterprise domains. Our team reviews anomalous results, especially for high-value accounts, to prevent incorrectly removing valid addresses.

What Teams Do With Email Validation

• Pre-campaign cleaning. Validate your email list before every campaign to maintain sender reputation and maximize deliverability.
• Sender reputation protection. Remove invalid, disposable, and role-based addresses that drag down your deliverability scores.
• Re-engagement campaign prep. Validate dormant contact emails before re-engagement campaigns. No point nurturing bounced addresses.
• CRM hygiene. Flag invalid emails across your entire CRM so your data team can prioritize re-enrichment for high-value contacts.
• Compliance. Verify email consent records against valid addresses. Invalid emails with opt-in records indicate potential data quality issues.
