How Leadrebel.io Achieved Cold Email Success with EmailListVerify

Cold email outreach is a powerful tool for lead generation, but without proper list management, emails can end up in spam folders or be blocked entirely. This is especially crucial for LeadRebel, a B2B lead generation software that helps businesses identify website visitors, gather detailed insights about them, and integrate these leads directly into their CRM or marketing/sales software of choice.

Since email outreach is a key part of the lead generation process, deliverability issues were causing significant challenges. High bounce rates and poor inbox placement were making it harder to connect with potential clients. To maintain a strong sender reputation and increase email engagement, LeadRebel integrated EmailListVerify to help them clean their email list, reduce bounces, and optimize outreach efforts.

The challenge: Avoiding blacklists and maintaining email reputation

Leadrebel.io relies on cold outreach to generate high-quality leads, but high bounce rates were putting their campaigns at risk. Invalid email addresses and poor inbox placement threatened their ability to reach potential customers effectively.

“To keep our domain reputation high and avoid getting banned or blacklisted, we needed a reliable email validation tool that was also affordable,” Leadrebel.io explains.

After evaluating multiple solutions, they chose EmailListVerify, citing its affordability and effectiveness compared to competitors.

Implementing EmailListVerify: Streamlining email validation

To maximize deliverability, Leadrebel.io integrated EmailListVerify into their existing tech stack, which includes Instantly and Apollo—two key platforms they use for managing cold email campaigns. By taking advantage of EmailListVerify’s API, they automated much of their email cleaning process, saving time and improving efficiency.

“Using EmailListVerify’s API has reduced the time spent on email validation and made our entire workflow more efficient,” they say. “We also appreciate that it’s a user-friendly interface, easy to understand even if you are newbie.”

The impact: More targeted outreach and fewer email issues

Since adopting EmailListVerify, Leadrebel.io has been able to fine-tune their outreach strategy and minimize unnecessary risks. Their results include:

• More precise targeting – Validated email lists allow them to focus on high-quality leads rather than wasting time on outdated or invalid addresses.

“With EmailListVerify, we can confidently contact the right email addresses without jeopardizing our sender reputation,” says Leadrebel.io.

Looking forward: Adapting to the future of cold email

Leadrebel.io anticipates that email deliverability will only get more challenging as email providers tighten restrictions. To stay ahead, they believe more advanced tools will be necessary, including:

• Spam sentence checkers to flag risky wording before sending emails.
• Enhanced inbox placement insights for better visibility on deliverability rates.
• Stronger verification for ‘Catch-all’ and ‘Unknown’ email addresses to improve accuracy.
