How to Ensure 99% Email Deliverability: A no2bounce Guide for Sales Teams

Did you know that 20% of B2B emails never reach their recipients? Invalid, catch-all, or mistyped emails silently sabotage your outreach efforts, wasting time and hurting your sender reputation. For sales teams, this means fewer replies, missed opportunities, and lower revenue.

The good news? With no2bounce’s email validation tools, you can eliminate bounce rates and ensure your messages land in inboxes - not spam folders. This guide will walk you through how to use no2bounce’s Single Validation and API integrations to clean your email lists, boost deliverability, and close more deals.

The Problem: Invalid Emails Hurt Your ROI

Before diving into the solution, let’s quantify the problem:

• Bounce rates for cold emails average 10-15%, but can spike to 30%+ with unverified lists.
• Catch-all domains (like those scoring 60 in no2bounce’s dashboard) may accept emails but often route them to oblivion.
• Invalid emails (scoring 0) are outright undeliverable - yet many CRMs let them slip through.

Example: In your no2bounce Single Validation History, emails like felicia.reid@example.com (Score: 0, Result: Invalid) and tanya.hill@example.com (Score: 60, Result: Catch-all) are red flags. Sending to these risks blacklisting and wastes sales efforts.

The Fix: no2bounce’s Validation Tools

1. Single Validation: Vet Leads Instantly

no2bounce’s Single Validation tool (shown in your dashboard) lets you manually check emails in seconds. Here’s how to use it:

• Paste an email (e.g., debble.baker@example.com) into the field.
• Review the Score (90 = valid, 60 = risky, 0 = invalid) and Result.
• Export clean lists or tag entries in your CRM.

Pro Tip: Use this for high-value leads before personalizing outreach.

2. Automate with API Integrations

For larger lists, automate validation using no2bounce’s API:

• Generate an API key (found in your API Settings tab).
• Integrate with tools like Salesforce, HubSpot, or Zoho (reference the Integrations screenshot).
• Set rules to flag or block invalid emails at entry.

Example Workflow:

• A lead submits a form → no2bounce API validates their email → Invalid emails are quarantined.

3. Pair with Your CRM for Full Protection

Sync no2bounce with your CRM to:

• Prevent invalid emails from clogging your database.
• Update lead scores based on email validity (e.g., “90” = ready to contact).
• Reduce spam complaints by pruning risky addresses.
