Clean your GetResponse contacts before they cost you twice
GetResponse stops mailing an address once it has already hard-bounced on a real send, but it can't judge an address before that first send - and those never-mailed invalids are exactly what erode your deliverability and pad the contact count your plan is priced on. Qualisend closes that gap: connect GetResponse, verify all your contacts or a single list, then use the results to delete and suppress the dead ones so junk never reaches a send and never sits on your bill. Here's how the native connector works, plus the CSV, API, and no-code options.
Connect GetResponse directly, no CSV needed
All you need is an API key
Paste your GetResponse API key. Find it in GetResponse under Menu → Integrations & API → API.
- Clean all contacts or a single list
- Results saved as custom fields on each contact
- New contacts checked in real time via webhook
- Auto-clean every 7, 14 or 30 days
Prefer CSV or the API? Both work too, see below.
What GetResponse cleans for you
GetResponse's native hygiene is reactive - it acts on the results of sends. Bounce management marks an address once it hard-bounces and stops mailing it, so a permanently dead mailbox isn't emailed campaign after campaign; alongside that, GetResponse monitors your account's bounce and complaint rates and will throttle or review a sender whose numbers climb, and it flags bounced and unsubscribed contacts rather than silently discarding them, so you stay compliant and don't re-mail someone who has already failed or opted out. For addresses GetResponse has actually mailed, that's dependable automatic hygiene.
What it can't catch
The catch is that every one of those mechanisms needs a send and a failure to fire. Never-mailed invalids from imports and signup forms, disposable addresses accepted at signup, role addresses, and decayed mailboxes all look healthy until your first campaign hits them - the send where the damage is done, and where a mailbox provider forms its first impression of your domain. An imported list is the sharpest case: it arrives with its bounce history stripped, so addresses that were already failing elsewhere look brand new, and GetResponse will happily store each one on your paid plan and deliver it straight into a hard bounce.
Why a clean GetResponse list matters
On GetResponse the stakes are double, because GetResponse bills by the number of contacts you store, not the emails you send. Every dead, duplicate, or never-opening address inflates the tier you pay for, and undeliverable addresses are the purest waste - you're paying to store mailboxes that will never receive a message, so removing enough of them can drop you into a lower tier and cut the bill. Reputation is the other half: a list full of never-mailed invalids turns your next campaign into a wave of hard bounces that dents your sender reputation, pushes the rest of your mail toward spam, and lifts the bounce and complaint rates Gmail and Yahoo's 2024 sender rules - and GetResponse's own sender reviews - judge you on. Cleaning before a send trims the bill and protects the inbox placement of the campaigns that actually convert.
Prefer CSV or the API? Here's the manual path
The native connector is the fastest route, but the CSV loop works on any GetResponse plan: export from GetResponse, verify in Qualisend, and act on the results.
Export your contacts from GetResponse
Open Contacts, search or filter to the list you want to clean - or build a segment first for a targeted maintenance clean - and export the contacts to CSV.
Verify the file in Qualisend
Upload the CSV to Qualisend bulk cleaning - up to 1,000,000 addresses, duplicates charged once - or paste addresses directly. The free plan's 100 credits cover a first sample before you commit the whole export.
Read the results
Every address returns deliverable, risky, undeliverable, or unknown with a reason code and sub-flags (catch-all, disposable, role, full mailbox), plus the MX provider and probe detail as evidence. Download the cleaned CSV.
Delete and suppress the undeliverables in GetResponse
Filter your results to undeliverable, use Contacts search to select the matching addresses, and remove them as a bulk action to drop them from your billable count - then add those same addresses, or whole domains, to a suppression list so a later import can't silently re-add a known-bad address. Both levers matter: delete alone risks a re-import, suppress alone keeps you paying to store a contact you'll never mail.
Or automate it at signup
Prefer to keep junk out from the start? Verify at the point of capture with the Qualisend REST API (scoped keys, rate limits, webhooks), or wire a no-code flow through Zapier, Make, or n8n so new GetResponse signups are checked before they're ever added - which keeps typos and disposable addresses out of your billable contact count entirely.
What Qualisend flags on every address
- Never-mailed invalid addresses that would hard-bounce on your next campaign
- Disposable / throwaway domains accepted at signup that were built to expire
- Role addresses (info@, support@) that skew engagement-judged automations
- Catch-all domains, flagged so you can segment and throttle them instead of suppressing
- A 0-100 confidence score and machine-readable reason code for every address

What to do with each result
Every address comes back with a verdict and sub-flags. Here's the action that keeps your GetResponse list clean without throwing away contacts you can still reach.
