Bad emails in Salesloft burn through cadence steps with no result. BounceZero verifies every address before it enters your cadence - so every step lands on a real inbox.
100 free verifications/month - No credit card required
Salesloft is built to multiply SDR output - but it multiplies whatever you feed it. Load a cadence with unverified contacts and it will diligently execute every email, call task and LinkedIn step against addresses that were dead before step one.
A 12-step Salesloft cadence executes 12 touches per contact - emails, call tasks, social steps. When an address bounces at step one, every downstream step is wasted SDR effort. With B2B emails decaying at 22% per year, a stale import can waste a fifth of your team's cadence capacity.
Salesloft sends through your own mailbox and domain. Every hard bounce chips away at that domain's reputation with Google and Microsoft - and mailbox providers start throttling senders at just a 2% bounce rate. Once flagged, even your valid contacts stop seeing your cadence emails.
SDR activity metrics, cadence conversion rates, and A/B tests all assume emails reached a human. When 15-30% of an unverified list is undeliverable, open and reply rates are measured against phantom contacts - so managers optimise cadences on noise instead of signal.
Every address destined for Salesloft passes through the full BounceZero pipeline - results in seconds, with a clear verdict and confidence score per contact.
We connect to the recipient mail server and confirm the exact mailbox exists - catching contacts who changed jobs before they ever consume a cadence step.
Around 23% of B2B domains accept all mail. Our 3-probe technique separates genuinely deliverable addresses from risky catch-all noise other tools mark "valid".
Flags info@, sales@ and admin@ addresses before they reach a cadence - low-intent inboxes that drag down reply rates and trigger spam complaints.
Identifies temporary and throwaway domains so they never enter your Salesloft cadences or skew your team's activity metrics.
Confirms the domain still has live, correctly configured mail servers - dead domains are a common failure mode in aging CRM and prospect data.
Screens against known spam trap patterns and recycled addresses. One trap hit can blocklist the domain behind your entire sales engagement stack.
Five steps from raw prospect list to a clean Salesloft import. A 10,000-contact file is verified in 5-10 minutes.
Export the contacts you plan to cadence - from Salesloft itself (People page > export to CSV), your CRM, or the prospecting tool feeding your pipeline. Keep the email column plus any fields you want to preserve.
Drag and drop the file into the BounceZero dashboard. We auto-detect the email column and deduplicate. Dashboard jobs up to 1,000,000 addresses are supported.
Each contact runs through all 6 checks - mailbox existence, catch-all 3-probe, role, disposable, MX, and spam trap screening. A 10K-row file completes in about 5-10 minutes.
Get your file back split into Valid, Risky (catch-all), and Invalid, with a confidence score per address - and every original column (name, account, title) intact for a clean re-import.
Re-import only the Valid segment into Salesloft, map your fields, and add the contacts to your cadence. Every step now executes against a real inbox, and your bounce rate stays under 0.5%.
Automating your Salesloft pipeline? Our real-time API responds with timing that varies by provider and verification path on average - verify each contact the moment it syncs into Salesloft from your CRM or enrichment tool.
$3 per 1,000 verifications. Compare that with what unverified bounces cost your sending domain, your Salesloft seats, and your SDRs’ time.

Common questions from revenue teams verifying Salesloft contacts with BounceZero.
Yes - via CSV workflow and API. Export contacts from Salesloft (or the CRM and prospecting tools feeding it) to CSV, upload to BounceZero, and re-import the cleaned file in minutes with all your original columns intact. For automated pipelines, our real-time API (provider-dependent response time) can verify each contact as it syncs into Salesloft, so nothing unverified ever enters a cadence.
Before importing. If a bad address never enters Salesloft, it can never consume a cadence step, generate a bounce from your domain, or pollute your team's activity metrics. Verifying at import also keeps your Salesloft People database clean over time, instead of accumulating dead contacts your SDRs keep re-cadencing.
Yes - more than most teams expect. Salesloft sends cadence emails through your own mailboxes and domain, so every hard bounce counts against your domain reputation with Google and Microsoft. Providers start throttling senders at around a 2% bounce rate; an unverified list typically bounces at 15-30%. Cleaned lists from BounceZero bounce at under 0.5%.
Around 23% of B2B domains are catch-all, meaning the server accepts mail for any address - so a simple SMTP check can't tell real from fake. BounceZero's 3-probe catch-all technique scores deliverability confidence for these addresses, so you can cadence high-confidence catch-alls and hold back the rest instead of discarding a quarter of your list.
Typically 5-10 minutes for a 10K-row file, and single dashboard jobs scale up to 1,000,000 addresses. Results come back segmented into Valid, Risky, and Invalid with a confidence score per address, and your original columns (name, account, title, phone) are preserved for a clean Salesloft re-import.
BounceZero costs $3 per 1,000 verifications with no subscription - cleaning a full 10K import costs $30. That's a fraction of one Salesloft seat, and you get 100 free verifications every month with no credit card, so you can test the workflow on a small segment before committing.
up to 99.8% accuracy in internal testing on SMTP-verifiable addresses. $3 per 1,000 verifications. Results in seconds. Start with 100 free verifications every month - no credit card required.
