—The hidden problem

Your bounce rate is silently destroying your sender reputation.

Your ESP charges you to send — whether the inbox exists or not. Every bounce ticks your sender score down. By the time Gmail puts you in the spam folder, the damage is months old.

is the bounce rate that gets you flagged

Most ESPs throttle your sends past this. Some suspend the account.

23%

of CSV uploads have at least one typo'd email

gmial.com, hotnail.com, yaho.com — your ESP doesn't catch these.

18%

of "valid-looking" addresses point to dead domains

DNS says nobody's home. You only find out from the bounce report a day later.

—The math

Bad addresses cost twice. Once in spend, once in trust.

You pay your ESP per email — sent or bounced. Then you pay again in sender reputation: throttled deliverability for the next campaign, then the one after that. Email is the channel that compounds — both directions.

—What you get

Eight checks. Two minutes. Zero bounces.

Read the spec

/01

Syntax

Catches the broken-on-arrival 1–3% before they ever leave your ESP. Strict RFC parser, normalised pre-flight, plus-tag and homograph aware.

/02

Live MX

Skips dead domains in real time so you stop emailing inboxes that don't exist. Authoritative DNS with 24h cache + negative TTL handling.

/03

Disposable

Blocks throwaway signups before they pollute your engagement metrics. 9,200+ providers, refreshed weekly.

/04

Role-based

Flags info@ / support@ — the addresses your ticketing system will silently swallow.

/05

Typo guard

Rescues real customers from `gmial.com` typos. Levenshtein against the top 1,000 free providers + your own domain pattern.

/06

TLD trust

Down-weights country codes and free-tier domains your sender score has never trusted.

/07

Suppression

Never re-mails a hard bounce. Cross-checked against your unsubscribe + bounce log every run.

/08

Historical

Tracks every address across runs so a previously-deliverable email that started bouncing gets caught next time.

—The platform

Eight checks are the engine. Here’s the rest of the dashboard.

Validation is half the job. The other half is the boring infrastructure around it — fixing typos so they don’t bounce, mapping columns to your ESP, comparing lists, automating it via API. All shipped, all included.

/01

Auto-repair, not just flag

Typo guard sees gmial.com → gmail.com, info@stripe.con → info@stripe.com. We don't drop them — we fix them, and you decide row-by-row what to keep.

How it works

pro/02

ESP-aware export mapper

Mailchimp wants Email Address. HubSpot wants email. Klaviyo wants $email. Pick your destination, we rewrite the CSV columns to match.

Supported ESPs

/03

Cross-list compare

Drop your suppression list. Drop your prospect list. We tell you what's new, what overlaps, and what to send — no spreadsheet acrobatics.

How it works

pro/04

Public API

POST /api/v1/clean. Bearer auth. Same engine as the dashboard, programmatic. Fits in any pipeline that talks HTTP.

API overview

pro/05

Webhooks

job.completed and dataset.ready fire the moment your run finishes. No polling, no client-side timers — just hand us a URL.

Event reference

/06

Per-row audit trail

Every rejection comes with the rule that flagged it. Hand the same CSV to compliance, your CMO, and the auditor — they all read the same column.

—From the founder

Built by someone who’d actually use it.

Damian

Reads every reply

I built DataBridge because I’d been working with email lists for years — client lists, my own projects, lists friends would send asking for a second look.

After enough time inside the workflow, I knew exactly what was missing.

Part of it was personal — I wanted to see if I could ship the version I’d actually want to use.

So this is it. Eight validation checks, live MX, typo auto-fix, list comparison, ESP-aware mapping. Free up to 1,000 rows a month. Pricing on the page.

If anything feels off or missing, reply to any email I send — it goes straight to my inbox.

—Questions

The questions before you sign up.

Didn’t find it? Email support@databridge.so — Damian reads every one.

Benchmarked at 99.1% for syntax + live MX combined, and 96.4% across all eight checks. Every flag travels with the row in the audit trail — you can see exactly which validator caught what.

We don't cut corners — same validators, same DNS, same accuracy. We're 10× cheaper because we don't pay for a sales team. Founder-built, founder-priced.

Encrypted in transit (TLS 1.3) and at rest (AES-256). The source file lives in your private storage — we don't aggregate it, we don't re-train on it, we don't resell suppression. Delete from /dashboard/datasets at any time and it's gone within 24h.

Yes — paid plans get a Bearer-auth public API at /api/v1/clean. Send a CSV, get a CSV (or JSON) back with verdict + reason per row. Webhooks fire on dataset completion. Full reference at /docs/api.

We never silently charge over. You'll see a paywall at 100% with the option to top up rows or upgrade. No surprise invoices, ever.

Cancel anytime from /dashboard/billing — your subscription stops at the end of the current period and you keep access until then. Email support@databridge.so within 7 days of a charge if something went wrong.

Send less. Reach more.

Drop a CSV in the next 60 seconds. We’ll hand it back cleaned, audited, and ready to send — for free.
