Benchmarks: What Does a Good Campaign Look Like?

Dealing with email deliverability presents significant challenges. Internet Service Providers actively filter spam to protect users, sometimes mistakenly flagging legitimate messages. Understanding spam filter algorithms — which operate predictably — enables you to maintain inbox placement.

Bounce Rates

Your email bounce rate has to be under 3 percent.

Achieving this requires dual focus: lead quality and email accuracy. Different market segments present varying challenges. Sales teams targeting niche audiences should cross-reference prospects against multiple databases and validate emails through tools like Neverbounce.

New email addresses face stricter scrutiny during initial outreach weeks, so keeping bounce rates low from the start is critical.

Reply Rates

Your reply rate must be above 3%.

Open rates no longer serve as meaningful metrics. Strong reply rates should begin immediately upon campaign launch. If you’re not hitting this threshold, consider:

Segmenting audiences more granularly
Tailoring messaging to specific pain points
Posing open-ended questions instead of meeting requests
Offering straightforward value propositions
Enabling opt-out through direct replies

Customized Messaging

Each email needs to be at least 30% different from the last one.

Balancing volume with personalization now prioritizes spam filter evasion over lead preference. Segmentation by industry, role, funding level, and technology stack provides foundational variation.

Additional tactics:

A/B testing different sequences
Using Spintax for automatic message variations
Varying subject lines across sends
Adjusting tone and CTA by segment

Spam Reporting

Under 0.1% of emails should be marked as spam.

Single complaints can damage entire campaigns. To stay below this threshold:

Avoid generic, automated-sounding messages
Space communications appropriately
Target specifically
Demonstrate genuine familiarity with prospects

The Four Benchmarks

Successful outbound campaigns require:

Bounce rates below 3%
Reply rates exceeding 3%
Minimum 30% email differentiation
Spam complaints under 0.1%

Hit all four consistently and your campaigns will compound over time.
