Native connector returning — CSV & API work today

Keep your Salesforce Marketing Cloud data extensions clean and deliverable

Marketing Cloud holds addresses that bounce enough to earn a Held status, but it can't judge an address it has never sent to — and the never-mailed invalids sitting in your data-extension imports and CRM syncs are exactly what erode a dedicated IP's reputation. Qualisend closes that gap: export a data extension, verify every address, and build a suppression data extension so junk never reaches a send. Here's the workflow that works today, plus the API and no-code options.

One-click Salesforce Marketing Cloud sync is paused while we rebuild the platform

We've deliberately paused our one-click native connectors while we re-engineer the sync layer they run on — hardening how we authenticate, respect each platform's rate limits, and write results back — so that when the native Salesforce Marketing Cloud integration returns, it stays dependable at any list size rather than fragile at scale. None of this touches how Qualisend verifies an address.

Everything you need works today: the CSV export → verify → reimport loop below, and the API for verifying at signup, are both fully supported and running in production — that's how teams keep Salesforce Marketing Cloud clean right now.

Salesforce Marketing Cloud handles

What Salesforce Marketing Cloud cleans for you

Marketing Cloud's native hygiene runs on subscriber status and account-level bounce management, tracked against your All Subscribers list. When an address hard-bounces, SFMC records it and moves the subscriber toward a Held status; an address that soft-bounces across enough consecutive sends escalates the same way rather than being retried forever. Held is applied at the account level, so a held subscriber is skipped on every future send that touches it. For addresses SFMC has actually mailed, that's reliable, automatic hygiene.

The gap it leaves

What it can't catch

The catch is that every one of those mechanisms is reactive — it needs a send and a bounce to fire. Records imported into a data extension from your CRM, another platform, or a purchased lead list have never bounced because they've never been sent to, so SFMC has no signal on them until your first send — which is exactly when a mailbox provider forms its first impression of your dedicated IP. A data-extension import is the sharpest case: it arrives with its bounce history stripped, so addresses that were already failing on the old platform look brand new in Marketing Cloud. And because Held is a status rather than a deletion, even a retired address still occupies a live row in every data extension that references it.

Why a clean Salesforce Marketing Cloud list matters

Cleaning pays off differently on Marketing Cloud than on a self-serve, monthly-billed ESP. SFMC is an enterprise platform: on most contracts you pay for contacts and super messages under an annual agreement, not a headcount that drops the moment you suppress a row — so cleaning your list won't shrink this month's invoice. What it protects is more valuable at scale. Every send to a dead address burns metered super message allowance you've already paid for and pushes you toward your contract's volume ceiling; each junk record inflates the contact totals your renewal is sized on; and, most importantly, sending to never-mailed invalids and recycled spam traps on a dedicated IP is precisely what erodes the sender reputation Gmail and Yahoo now judge you on at the door. Reputation is far more expensive to rebuild than a list is to verify.

The workflow that works today

Direct connectors are paused while we rebuild the platform, so the dependable path is the CSV loop: export from Salesforce Marketing Cloud, verify in Qualisend, reimport the clean file.

1

Export a data extension from Marketing Cloud

Pull the data extension or segment you want to clean out to a CSV — through a data extract in Automation Studio, or the export tools in your account's contacts and email area — making sure the email address column is included.

2

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.

3

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.

4

Build a suppression data extension in Marketing Cloud

SFMC retires addresses through exclusion, not a delete button: filter your results to undeliverable (plus the disposables you don't want to keep), import those addresses into a dedicated suppression data extension, and apply it as an exclusion at send time. Keep it current with a SQL Query Activity in Automation Studio so it refreshes on a schedule — the dead addresses stay retired without deleting the source records.

Or automate it at signup

Prefer to keep junk out before it ever reaches a data extension? 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 subscribers are checked before they're written into Marketing Cloud.

What Qualisend flags on every address

Native connector status

A native, one-click Marketing Cloud connector is part of the platform we're rebuilding — it's returning, not deprecated. Until it ships, the CSV loop above and the API are the fully supported path, and they work with any Marketing Cloud edition.

What to do with each result

Every address comes back with a verdict and sub-flags. Here's the action that keeps your Salesforce Marketing Cloud list clean without throwing away contacts you can still reach.

deliverableKeep sending as normal.
deliverable + role flagKeep for transactional and account mail; exclude from engagement-scored journeys.
risky + catch-all flagMove to a dedicated data extension and throttle rather than blasting.
risky + disposable flagAdd to the suppression data extension — the inbox was built to expire.
unknownKeep active and re-verify next clean — usually greylisting or rate-limiting, not a verdict on the mailbox.
undeliverableAdd to the suppression data extension; don't wait for the bounce to prove it.
