This article will provide information and best practices on the new, Catch-All status for the LS Person Original Email Verification field.

What are Catch-All Emails?

Catch-All emails are domains that accept all incoming emails, even invalid ones. This makes them tricky to handle, as they do not guarantee deliverability. Breaking out Catch-All emails out of the 'Invalid' status was a decision made by Leadspace to give Marketing and Sales Teams more control over how to handle these types of email domains.

For example, if your company is not terribly concerned with sender reputation, then you may be encouraged to treat 'Catch-All' emails like 'Valid' emails and add them to your sender lists and campaigns. However, if sender reputation and bounce rate are of concern, then you may want to be more cautious in utilizing these emails.

How to Treat and Manage Catch-All Emails 

The following details outline some Leadspace best practices on how to use and incorporate Catch-All emails into your Marketing and Sales processes. We highly encourage you to do some independent research on Catch-All emails in order to make the most informed decisions for your respective business practices and needs.

Monitor Deliverability and Engagement

Catch-All addresses may increase your bounce rate, which can hurt your sender reputation over time.

• Send small test campaigns to Catch-All emails first. Track opens, clicks, and bounces carefully.
• Keep only those addresses that show engagement (opens/clicks) in subsequent campaigns.
• If an email bounces, remove it immediately to keep your list clean and maintain a good sender reputation.
•  

Segment Your Email List

Treat Catch-All emails as a separate segment within your overall list.

• Include Catch-All emails in lower-priority campaigns or in emails where deliverability risks are manageable.
• Avoid including Catch-All addresses in critical campaigns like transactional emails.

Test Before Larger List Sends

Sending to a high volume of Catch-All emails at once can negatively impact deliverability.

• Run small test batches to Catch-All domains to gauge bounce rates and engagement.
• Adjust your strategy based on the results of these test sends

Combine With List Hygiene Practices

Even if a Catch-All email initially validates as “deliverable,” its status can change. Regular list cleaning is essential.

• Validate your email list periodically to ensure it remains up-to-date.
• Remove Catch-All addresses that haven’t engaged over a set timeframe (e.g., 3–6 months).

Catch-All emails can be valuable but come with risks. By combining list segmentation, hygiene practices, and careful monitoring of engagement, you can include Catch-All emails strategically without compromising your sender reputation.
