Does Qualisend have a native Braze integration?

A native one-click connector is being rebuilt as part of our platform upgrade and will return. Today the supported path is the export loop — export from Braze (dashboard CSV or the /users/export/segment API), verify in Qualisend, then set the undeliverables' email subscription state to unsubscribed — or verifying at the point of capture through the API. Both work with any Braze package.

Will cleaning my list lower my Braze bill?

Not directly, and we won't pretend otherwise. Braze prices on monthly active users, data points, and message volume rather than the number of contacts you store, so suppressing a dead email doesn't remove a per-contact line item the way it would on Mailchimp or Constant Contact. The payoff is real but different: you stop spending message volume delivering into hard bounces — waste that Braze's event-driven re-entry repeats on every trigger — and you protect the sender reputation that decides inbox placement for your whole audience. Suppression itself costs nothing either way, since Braze doesn't charge data points for a subscription-status change.

Should I unsubscribe or delete a bad address in Braze?

For a verified undeliverable, set its email subscription state to unsubscribed — via a CSV re-import with an email_subscribe column or the /email/status endpoint. That stops every campaign and Canvas from mailing it while keeping the profile and its record, so a later event or import can't silently flip it back to mailable. Reserve /users/delete for genuine junk, because deletion also erases the profile's event history — and on MAU-based billing it won't meaningfully change your bill.

Can I verify addresses before they enter Braze?

Yes, and on an SDK/API-driven platform it's the highest-leverage option. Verify at the point of capture through the REST API (or a Zapier/Make/n8n flow) so an address is checked before your identify or track call writes it into a Braze profile — that way typos and disposable addresses never become mailable users and never enter a Canvas in the first place.

Keep your Braze audience clean before the first send bounces

Q: How do I export my Braze audience to verify it?

Two ways. In the dashboard, open a segment, use the User Data dropdown, and choose CSV Export Email Addresses; Braze emails you a download link when the file is ready (you need the Export user data permission, and dashboard exports can fail once a segment is estimated above roughly 500,000 users). For larger audiences or an automated pipeline, call the /users/export/segment API, which is asynchronous and returns newline-separated JSON to a URL or S3 — extract the email field into a CSV column before uploading to Qualisend.

Braze marks a hard-bounced address invalid and stops sending to it, so it reacts to a known-bad address after the first failure — but it can't judge an address before that first send. And Braze is API- and SDK-driven: a profile appears the moment your app fires an identify or track call, so never-messaged invalids from your SDK, an import from a previous ESP, or a signup typo look perfectly mailable until an event triggers their debut message — exactly when a mailbox provider forms its first impression of your domain. Qualisend closes that gap: export your audience, verify every address, and suppress the dead ones before they ever enter a Canvas. Here's the workflow that works today, plus the API and no-code options.

One-click Braze 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 Braze 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 Braze clean right now.

Braze handles

What Braze cleans for you

Braze's native hygiene runs on two things: the global email subscription state and the bounce list. Every profile carries an email_subscribe state — opted_in, subscribed, or unsubscribed — and Braze won't send marketing email to an unsubscribed profile. When someone unsubscribes through your footer link or a list-unsubscribe header, Braze sets their global email subscription state to unsubscribed automatically. Separately, when an address hard-bounces, Braze marks it invalid, adds it to your bounce list, and stops attempting delivery — note that a hard bounce does not flip the subscription state, it simply flags the address as undeliverable so it's skipped on future sends. Spam complaints are treated the same way. For addresses Braze has actually messaged, 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 failure to fire. Braze makes the blind spot sharper because it's event-driven: a profile is created the instant your app fires an identify or track call, so addresses from your SDK, an import from a previous ESP, or a signup typo (jane@gmial.com) have never bounced because they've never been messaged. Disposable addresses, role addresses (info@, support@), catch-all domains, and mailboxes that have decayed since capture all sit at email_subscribe = subscribed, fully mailable, until an event finally triggers their first message. Worse, because Braze re-enters people into Canvases and campaigns every time an event matches, a dead address doesn't fail once and vanish — it gets mailed again and again, compounding the bounce signal. An imported audience is the sharpest case: it arrives with its bounce history stripped, so addresses that were already failing on your old platform look brand new to Braze.

Why a clean Braze list matters

Braze doesn't bill by the contact — it prices on monthly active users, data points, and message volume — so unlike a contact-count ESP, suppressing a dead address won't shrink a per-contact invoice, and we won't pretend it will. The payoff here is deliverability and wasted sends, not a smaller line item. Every never-messaged invalid you leave mailable is a send spent delivering straight into a hard bounce, and Braze's event-driven re-entry means that waste repeats on every matching trigger rather than happening once. More importantly, each of those bounces is exactly the signal Gmail and Yahoo's 2024 bulk-sender rules — and your own deliverability monitoring — judge you on: cross their bounce-rate threshold and inbox placement drops for every subscriber, including the ones you earned honestly. At enterprise sending volume that reputation hit costs far more than the wasted sends themselves. Cleaning before the send keeps the message volume and the reputation intact — and because Braze doesn't charge data points for a subscription-status change, suppressing the failures costs you nothing on the bill either.

The workflow that works today

Braze is an API/SDK and data-pipeline driven platform, so the reliable path is: export your audience with the dashboard CSV export or the /users/export/segment API, verify it in Qualisend, then suppress the failures by setting their email subscription state to unsubscribed via a CSV re-import or the /email/status API.

Export your audience from Braze

Open the segment you want to clean and use the User Data dropdown to run a CSV Export Email Addresses — it returns one row per user in the segment who has an email. Braze builds the file in the background and emails a download link to the dashboard user who requested it, so you'll need the Export user data permission, and dashboard exports can fail once a segment is estimated above roughly 500,000 users. For larger audiences or an automated pipeline, use the /users/export/segment API instead — it's asynchronous and built for bigger pulls, returning newline-separated JSON user objects to a generated URL or your S3 bucket.

Verify the file in Qualisend

Upload the CSV to Qualisend bulk cleaning — up to 1,000,000 addresses per job, duplicates charged once — or paste addresses directly. The free plan's 100 one-time credits, which never expire, cover a first sample. If you exported JSON from the API, pull the email field into a CSV column first.

Read the results

Every address returns deliverable, risky, undeliverable, or unknown with a reason code, a 0–100 score, and sub-flags (catch-all, disposable, role, full mailbox), plus the MX provider and probe detail as evidence. Download the cleaned CSV.

Suppress the undeliverables in Braze

Filter the results to undeliverable. The no-code path is a CSV import: keep the email column, add an email_subscribe column set to unsubscribed, and re-import — Braze sets those profiles' global email subscription state to unsubscribed so they drop out of every campaign and Canvas (watch for trailing spaces and capitalization, which Braze rejects as invalid). To automate it, POST the same addresses to the /email/status endpoint in batches of up to 50 with subscription_state unsubscribed (email.status permission). Neither the CSV column nor the /email/status call incurs data-point charges, so suppression itself is free. Braze's bounce list only catches these after they fail a real send, so this does the reputation-saving work up front; reserve /users/delete for genuine junk, since deletion also erases the profile's event history.

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 an address is checked before your app's identify or track call ever writes it into a Braze profile — so typos and disposable addresses never become mailable users or reach a Canvas.

What Qualisend flags on every address

Never-messaged invalid addresses that would hard-bounce the first time an event triggers a send
Disposable / throwaway domains accepted at signup that were built to expire
Role addresses (info@, support@) that skew the engagement data your Braze segments and Canvases branch on
Catch-all domains, flagged so you can route them to a dedicated segment and throttle
A 0–100 confidence score and machine-readable reason code for every address

Native connector status

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

What to do with each result

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

deliverableKeep messaging as normal.

deliverable + role flagKeep for transactional and account mail; exclude from engagement-judged Canvases.

risky + catch-all flagMove to a dedicated segment and throttle — the domain accepts everything at the door, so the mailbox behind it can't be confirmed.

risky + disposable flagSet email_subscribe to unsubscribed — the inbox was built to expire.

unknownKeep subscribed and re-verify next clean — usually greylisting or rate-limiting, not a verdict on the mailbox.

undeliverableSet the global email subscription state to unsubscribed (CSV re-import or /email/status); don't wait for the bounce list to prove it.
