How to Clean Your GetResponse List and Reduce Bounce Rate

GetResponse is one of the most popular email marketing platforms for small businesses, e-commerce stores, and solopreneurs. But even the best ESP cannot protect you from a dirty list. If your bounce rate climbs above 2%, GetResponse starts throttling your sending. Push past 5% and your account may be suspended entirely.

The fix is straightforward: validate your list before you send. This guide walks you through exactly how to do that.

Why Bounce Rate Matters in GetResponse

GetResponse tracks hard bounces and soft bounces separately, but both count against your sender reputation. A hard bounce means the email address is invalid or does not exist. A soft bounce usually means a temporary issue, like a full inbox or a server timeout.

When too many messages bounce, inbox providers like Gmail and Outlook flag your sending domain as unreliable. Your future emails land in spam, even for subscribers who genuinely want your content. Cleaning your list fixes the root cause rather than treating the symptom.

Common Sources of Bad Emails in GetResponse

Before cleaning, it helps to understand where bad addresses come from:

• Lead magnets and free giveaways: People enter throwaway email addresses to access a freebie without committing to ongoing emails.
• Old imported lists: If you imported a CSV from a trade show, webinar, or CRM years ago, many of those addresses have gone cold or been abandoned.
• Catch-all corporate domains: Many B2B addresses route to a catch-all inbox. Standard validators mark these as valid, but they often bounce in practice.
• Typos at signup: gmial.com, yaho.com, and hotmial.com are classic examples that slip through basic form validation.

Step 1: Export Your GetResponse List

Log in to your GetResponse account and navigate to Contacts. Select the list you want to clean, then use the Export option to download your subscribers as a CSV file. Make sure to include the email address column and any custom fields you want to preserve.

For large lists, GetResponse will email you a download link once the export is ready.

Step 2: Validate the List with Scrubby

This is the most important step, especially if your list contains B2B addresses or was imported from a third-party source.

Scrubby specializes in validating catch-all and risky email addresses that standard validators skip or misclassify. Most email verification tools simply mark catch-all domains as “unknown” and leave you guessing. Scrubby actually probes those addresses and tells you whether they are deliverable or not.

Upload your exported CSV to Scrubby, let the verification run, and download the results. The output will tag each address as valid, invalid, risky, or catch-all with a deliverability probability score.

Remove any address tagged as invalid. For risky and catch-all addresses, use the probability score as your threshold. A common practice is to suppress any address below 70% probability for campaigns where deliverability is critical, such as transactional emails or re-engagement flows.

Step 3: Segment by Risk Level in Your Results

Once you have the Scrubby results, split your contacts into three groups before reimporting:

1. Safe to send: Valid addresses with high deliverability scores. Reimport these as your main active list.
2. Monitor closely: Catch-all addresses above your probability threshold. You can keep these on your list but watch their individual bounce and engagement metrics after your next send.
3. Suppress immediately: Invalid addresses and anything below your probability threshold. Do not reimport these.

This segmentation approach protects your sender score without forcing you to delete borderline addresses outright.

Step 4: Reimport the Cleaned List to GetResponse

In GetResponse, go to Contacts and use the Import option. Upload your cleaned CSV and map the columns to the correct fields. GetResponse will automatically deduplicate existing contacts, so only new or updated records will be added.

After importing, archive or delete the original unvalidated list so you do not accidentally send to it in the future.

Step 5: Enable Double Opt-In for New Subscribers

Cleaning your existing list solves the historical problem. Double opt-in prevents the problem from recurring.

In GetResponse, go to Forms and Surveys or your automation settings and enable the confirmation email for new subscribers. Anyone who signs up through your opt-in form must click a confirmation link before they are added to your active list. This eliminates typos and disposable addresses at the point of entry.

Double opt-in typically reduces list growth by 20-30%, but the addresses you keep are far more engaged and far less likely to bounce.

Step 6: Set Up a Re-engagement Flow Before Removing Inactive Subscribers

Inactive subscribers, those who have not opened or clicked in 90 to 180 days, inflate your list size without contributing to engagement. GetResponse’s automation builder lets you create a simple re-engagement sequence:

1. Send a “We miss you” email asking subscribers to confirm they still want to hear from you.
2. Wait 7 days. If no engagement, send a final “Last chance to stay subscribed” email.
3. If still no engagement after another 7 days, move them to a suppression list.

This process recovers a small percentage of genuinely interested subscribers while removing the dead weight that drags down your open rates and deliverability scores.

How Often Should You Clean Your GetResponse List?

For most senders, a quarterly validation cycle works well. If you run aggressive lead generation campaigns, run a Scrubby validation on every new batch before it touches your main list. For high-volume senders (100,000+ emails per month), monthly validation is worth the cost.

The signal to clean immediately: if your last campaign in GetResponse showed a bounce rate above 1.5%, run a full validation before your next send.

The Deliverability Stack That Actually Works

Email list hygiene is one layer of a broader deliverability strategy. If you want to go deeper, look at your DNS records (SPF, DKIM, DMARC), your sending volume ramp-up schedule if you are on a new domain, and your unsubscribe rate alongside your bounce rate.

For teams running multi-channel outreach alongside email, tools like Kali can help you book demos through calendar invite outreach rather than relying solely on email volume to drive pipeline.

Summary

Cleaning your GetResponse list comes down to four actions: export your current list, validate it with a tool like Scrubby that handles catch-all addresses, reimport only the deliverable contacts, and turn on double opt-in to stop bad addresses from entering in the first place. Do this before your next campaign and your bounce rate will drop, your open rates will climb, and GetResponse will keep your account in good standing.
