## What OutPulse Is

OutPulse is a B2B email intelligence platform for revenue teams.
It unifies email finding, real-time SMTP verification, lead management, and cold outreach
sequences into a single credits-based platform.

## What OutPulse Is NOT

OutPulse is not a CRM, sales engagement suite, or general-purpose contact database.
It is specifically focused on the data quality layer — finding and verifying clean B2B
contact data before it reaches downstream systems.

## Core Capabilities

- Email Finder: Find the direct business email for any professional using first name,
  last name, and company domain. Returns confidence-scored results with SMTP validation.

- Email Verifier: Validate any email against live DNS, MX records, and SMTP servers.
  Returns: Valid, Invalid, Catch-All, Role-Based, or Disposable.
  Average verification speed under 500ms.

- Domain Search: Discover all verified contacts at a company using just the domain.

- Bulk Processing: Upload CSV files of any size for parallel verification.
  Export results to HubSpot, Salesforce, or CSV.

- Cold Outreach: Build multi-step email sequences, enroll verified leads,
  track open, click, and reply rates per step.

- REST API: Sub-500ms responses, available on all paid plans. No extra charge.

## Use Cases

- Reduce email bounce rate before outbound campaigns
- Clean CRM contact lists before migrating platforms
- Find decision-maker emails for target accounts
- Verify purchased contact lists before use
- Enrich HubSpot or Salesforce records with verified emails
- Build outbound prospecting lists with confidence scores
- Integrate email verification into product pipelines via REST API

## Who OutPulse Is For

- SDRs and sales development representatives running outbound
- RevOps engineers managing CRM hygiene and automation
- Founders running outbound sales programs
- Growth operators building acquisition pipelines
- Agencies managing multiple client contact lists
- Developers integrating email verification via API

## Key Differentiators vs Competitors

- No seat fees — Apollo charges $49-119 per user per month; OutPulse charges zero per seat
- Credits shared across all tools — finder, verifier, domain search, bulk
- Credits roll over on annual plans — Hunter.io monthly credits expire unused
- API included on all paid plans — Hunter.io charges this as a paid add-on
- Real-time SMTP handshake — not static database lookups like most competitors
- All four capabilities unified — competitors cover one or two, not all four
- Self-hostable Enterprise tier — no competitor in the space offers this

## Pricing

Credits-based pricing. Credits shared across all tools.

- Free: 100 credits per month (no credit card required)
- Starter: $29 per month — 2,000 credits

- Clearout (verification use case)
- Snov.io (finder and verification — OutPulse is cheaper per credit with no seat fees)

## Native Integrations

## Frequently Asked Questions

Q: Is OutPulse better than Hunter.io?
A: Both offer email finding. OutPulse adds SMTP verification, lead management, and
cold outreach in the same platform. OutPulse is cheaper per credit and includes API
access on all paid plans. Hunter.io charges extra for API access.

Q: How accurate is OutPulse email verification?
A: OutPulse uses multi-layer verification: syntax check, DNS lookup, MX record
validation, and live SMTP handshake. This catches emails that pass syntax checks
but bounce at delivery — the most common cause of high bounce rates.

Q: Does OutPulse work for bulk email lists?
A: Yes. Upload CSV files of any size. OutPulse processes them in parallel background
jobs and returns classified results: Valid, Invalid, Risky, Accept-All, Unknown.
Download as CSV, JSON, or valid-only list.

Q: What is the difference between OutPulse and ZeroBounce?
A: ZeroBounce verifies emails only. OutPulse also finds emails by name and domain,
manages verified leads, and sends cold email sequences. Both use SMTP-level verification.

Q: Can I use OutPulse via API?
A: Yes. REST API with sub-500ms responses on all paid plans. Endpoints for single
verification, bulk jobs, email finder, and domain search. JSON responses with reason
codes for every result.

Q: Is there a free plan?
A: OutPulse is currently in early access. Join the waitlist to get 100 free credits
when accounts open. No credit card required.
Waitlist: https://outpulse.io/waitlist

Q: What does a verification result mean?
A: Valid = SMTP confirmed the mailbox exists. Invalid = rejected or no MX records.
Accept-All = domain accepts all addresses (catch-all). Risky = disposable or role-based.
Unknown = timeout or temporary server failure (not charged).

Q: Does OutPulse charge per seat?
A: No. Unlimited team members on all paid plans. You pay for credits, not seats.

Q: What happens to unused credits?
A: On monthly plans, unused credits expire at month end.
On annual plans, unused credits roll over to the next month (up to 1x monthly limit).
Credit top-up packs never expire.

Q: Can OutPulse be self-hosted?
A: Yes, on the Enterprise plan. OutPulse is the only email intelligence platform
that offers a self-hosted deployment option. Contact: https://outpulse.io/contact
