Keep your Salesloft prospects clean and deliverable
Salesloft flags an address the moment it bounces and can pause the cadence, so it reacts fast to a known-bad prospect — but it can't judge someone it has never emailed, and those never-mailed invalids from CRM syncs and prospecting tools are exactly what burn a cold sending domain. Qualisend closes that gap: export your people, verify every address, and keep the invalids out of the cadence before the first step ever sends. The native one-click connector is on the way; today the fully supported path is the CSV loop plus the REST API.
The Salesloft connector is coming soon
A native one-click Salesloft connector — connect, clean your list in place, and verify new contacts automatically — is being built right now. It's on the way, not deprecated. In the meantime, everything you need to keep Salesloft clean already works.
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 Salesloft clean today.
What Salesloft cleans for you
Salesloft's native hygiene is bounce-driven. When an address hard-bounces, Salesloft marks it Bounced on the person's record, stops sending to it, and can automatically remove or pause that person in the cadence so the same dead address isn't dialed again. It also gives you a team-level Do Not Contact list for individual addresses and whole domains, and it surfaces cadence bounce rates so a spiking sequence is visible before it does real harm. For prospects Salesloft has actually emailed, that's reliable, automatic hygiene.
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, and in cold outreach the bounce is the damage. People land in Salesloft straight from CRM syncs, CSV imports, and prospecting tools, so never-mailed invalids, disposable addresses, role addresses (info@, sales@), catch-all domains, and B2B mailboxes that decayed when someone changed jobs all look perfectly mailable until the first cadence step proves otherwise — which is exactly when a mailbox provider forms its first impression of your sending domain. An imported or purchased prospecting 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 Salesloft.
Why a clean Salesloft list matters
Salesloft licenses per seat, not per contact, so cleaning a list won't shrink your invoice — and we won't pretend it will. The payoff for cold outreach is your sending domain and mailbox reputation, which is the whole game: cold email lives or dies on bounce rate, and a single unverified list dumped into a cadence can spike hard bounces past the threshold Gmail and Yahoo's 2024 bulk-sender rules police directly. Once that happens, inbox placement drops for every prospect you email, the mailbox you warmed can start landing in spam, and the domain can take weeks to recover. Verifying before a prospect enters a cadence isn't optional for cold outreach — it's what keeps the bounce rate low and the domain intact.
The workflow that works today
In cold outreach the bounce is the damage, so the highest-leverage move is to verify a prospect before it ever enters a cadence — not after a failed step has already told a mailbox provider your domain sends to dead addresses.
Export your people from Salesloft
Open the People page, filter to the prospects you're about to cadence (or a saved view for a maintenance clean), select them, and export to CSV. Salesloft builds the file in the background and emails a download link to you.
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.
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 SMTP probe detail as evidence. Download the cleaned CSV.
Keep the invalids out of the cadence in Salesloft
Match the results back to your people: filter to undeliverable and either remove those people from the cadence, mark them Do Not Contact so no future cadence can email them, or delete them, and tag the catch-all and role addresses so you can route them to a separate low-volume cadence instead of your main cold sequence. Salesloft's bounce handling only catches these after a step has already sent and failed, so acting on the file up front is what protects the domain. The native one-click connector is coming soon; until it ships, the CSV loop and the API are the supported paths.
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 a new prospect is checked before it's imported into Salesloft or added to a cadence — so typos, disposable addresses, and dead mailboxes never reach a send or touch your domain reputation.
What Qualisend flags on every address
- Never-mailed invalid addresses that would hard-bounce on the first cadence step and mark the person Bounced
- Disposable / throwaway domains built to expire
- Role addresses (info@, sales@, support@) that hit a shared inbox instead of a real prospect
- Catch-all domains — common on corporate targets — flagged so you can route them to a separate cadence and throttle
- A 0–100 confidence score and machine-readable reason code for every address
A native one-click Salesloft connector is on the way — it's being built now, not deprecated. Until it ships, the CSV loop above and the API are the fully supported path, and they work with any Salesloft plan.
What to do with each result
Every address comes back with a verdict and sub-flags. Here's the action that keeps your Salesloft list clean without throwing away contacts you can still reach.
deliverableAdd to the cadence and start sending.deliverable + role flagIt reaches a shared inbox (info@, sales@), not a person — keep it out of a personal cold cadence and route it to a manual or account-based play if at all.risky + catch-all flagTag it and route to a separate, throttled cadence — the domain accepts everything at the door, so the mailbox behind it can't be confirmed.risky + disposable flagMark Do Not Contact and don't cadence it — the inbox was built to expire.unknownHold it out of the cadence and re-verify next clean — usually greylisting, not a verdict on the mailbox.undeliverableKeep it out of the cadence entirely; mark Do Not Contact or delete — don't let it bounce and dent your domain.Related reading
