Does Qualisend have a native Ortto integration?

Yes. The native Ortto connector is live: connect Ortto directly in Qualisend and clean your CDP in place, verifying people and writing the results back as a suppression, an archive, or a tag, with real-time verification of new contacts and scheduled re-cleans. The CSV loop and REST API remain available for one-off exports or point-of-capture checks, and everything works on any Ortto plan.

How many addresses can I verify at once?

Bulk cleaning handles up to 1,000,000 addresses per job with live progress, and duplicates are charged once. The free plan includes 100 one-time credits that never expire, enough for a first sample.

Can I verify addresses before they enter Ortto?

Yes, and it's the highest-leverage option. Verify at the point of capture through the REST API or a Zapier, Make, or n8n flow, or let the native connector check new contacts in real time, so typos and disposable addresses never enter your CDP in the first place.

Will cleaning my list lower my Ortto bill?

It can. Ortto bills on total contact count and counts every record regardless of status, so unsubscribed and bounced contacts keep costing you until you archive them. Archived contacts drop off your billable count, so archiving the undeliverable and disposable addresses you'll never reach again can move you back under a pricing step.

Should I suppress, archive, or delete on Ortto?

They do different jobs. Adding an address to the email suppression list stops all future sends but doesn't remove it from your billable count; archiving is what takes a contact off your plan total while keeping the record viewable and exportable. For dead addresses, do both: suppress to stop sends immediately, then archive to reclaim the billing slot.

Native one-click sync — live

Keep your Ortto contacts clean and deliverable

Ortto automatically unsubscribes an address the moment it hard-bounces or draws a spam complaint, so it reacts fast to a bad mailbox, but it can't judge an address it has never emailed, and the never-mailed invalids from imports and signup forms are what quietly erode your deliverability. Qualisend closes that gap with a live native connector that cleans your CDP in place: verify every person and write the results straight back as a suppression, an archive, or a tag, with new contacts checked in real time and scheduled re-cleans. A CSV loop and the REST API cover every other case.

Native connector

Connect Ortto and clean it in place

Connect Ortto with an API key and Qualisend verifies the lists you already have — right inside Ortto, no export. Dead and risky addresses are suppressed or archived for you, every new subscriber is checked in real time, and you can re-verify on a schedule so the list never drifts back to dirty.

Prefer to work by hand, or verify at signup through your own stack? The CSV export → verify → reimport loop below and the REST API are fully supported too.

Ortto handles

What Ortto cleans for you

Ortto's native hygiene runs on subscription status and bounce handling. When an address hard-bounces or a recipient marks your email as spam, Ortto automatically unsubscribes that person from future emails to protect your sender reputation, and unsubscribes are honored across every campaign and journey. Ortto also gives you a manual email suppression list you can import into, choosing whether an address is blocked from all emails or from transactional email only. For addresses Ortto 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. 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, which is exactly when 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 on another platform look brand new to Ortto.

Why a clean Ortto list matters

On Ortto the stakes are double, because Ortto bills on your total contact count and it counts every record regardless of status. An unsubscribed or hard-bounced contact keeps costing you until you archive it, so Ortto's own auto-unsubscribe protects your reputation but never your bill. Cleaning and archiving the dead can move you back under a pricing step, and it protects the inbox placement that Gmail and Yahoo's 2024 bulk-sender rules, which police your bounce and complaint rates, judge your domain on.

Prefer CSV or the API? Here's the manual path

The live native connector is the fastest path, verifying and retiring addresses inside your CDP automatically; the manual CSV loop below runs the same four steps and works on any Ortto plan.

Export your people from Ortto

In Ortto, go to CDP > People and build a filter or audience for the list you want to clean, then choose More > Export, pick all data, and export. Ortto emails the CSV to the address on your account.

Verify the file in Qualisend

Upload the CSV to Qualisend bulk cleaning, up to 1,000,000 addresses with duplicates charged once, or paste addresses directly. The free plan's 100 credits, which never expire, cover a first sample.

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 SMTP probe detail as evidence. Download the cleaned CSV.

Suppress and archive the undeliverables in Ortto

Filter your results to undeliverable and import that list into Ortto's email suppression list under CDP, choosing the all-emails status so those addresses are held out of every campaign and journey. Then archive the same people, because Ortto counts bounced and unsubscribed contacts toward your plan until you archive them, and archived records drop off your billable count.

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 Zapier, Make, or n8n flow so a new Ortto person is checked before it's created, and the native connector already verifies new contacts in real time so typos and disposable addresses never reach a send or your contact count.

What Qualisend flags on every address

Never-mailed invalid addresses that would hard-bounce on your next campaign and auto-unsubscribe the person in Ortto
Disposable / throwaway domains built to expire
Role addresses (info@, support@) that skew engagement-judged journeys
Catch-all domains, flagged so you can move them to a dedicated audience and throttle your sends
A 0–100 confidence score and machine-readable reason code for every address

Native connector status

The native Ortto connector is live — connect it in Qualisend under Integrations and clean your list without a single CSV. New contacts are verified automatically, and you can re-verify on a schedule.

What to do with each result

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

deliverableKeep sending as normal.

deliverable + role flagKeep for transactional content; exclude from engagement-judged journeys by tagging the person.

risky + catch-all flagMove to a dedicated audience and throttle your sends.

risky + disposable flagSuppress or archive; the inbox was built to expire.

unknownKeep active and re-verify next clean, usually greylisting or rate-limiting rather than a verdict on the mailbox.

undeliverableAdd to Ortto's email suppression list and archive the person; don't wait for the bounce to prove it.
