Land in the inbox.
Sendvela watches your sender reputation, authentication, warmup, and inbox placement from one bridge — on top of the MTAs and ESPs you already run. No migration, no new sending stack.
34 integrations — Postfix, PowerMTA, KumoMTA, SES, SendGrid, Mailgun and more.

The problem
Deliverability fails quietly. You find out from falling revenue, not from your tooling.
A lapsed DKIM key, a warming schedule that outran your reputation, a blocklist listing nobody checked — each one silently reroutes your mail to spam. Sendvela's seven modules exist to make every one of those loud, early, and fixable.
Module 01Compass
The deliverability dashboard. Reputation score, trend lines, and the exact signals dragging them up or down — at a glance, per domain and per tenant.
Module 02Trim
Automated mailbox warmup with safe, gradually increasing send schedules — so new domains earn reputation instead of tripping filters on day one.
Module 03Windcheck
Live SPF, DKIM, DMARC, and MX validation. When authentication drifts — a rotated key, a changed include — you hear about it before mailbox providers do.
Module 04Harbor
Inbox placement monitoring. Seed addresses across Gmail, Outlook, Yahoo and more show exactly where your mail lands — inbox, promotions, or spam.
Module 05Beacon
Reputation and placement alerts, tuned to fire while a problem is still small — before a dip becomes a blocklist and a blocklist becomes a crisis.
Module 06Relay
Bring your own MTA — Postfix, Exim, PowerMTA, KumoMTA, Halon and more — with per-tenant credentials and SSRF-guarded config resolution.
Module 07Logbook
The one no competitor ships: every signal — blacklists, Postmaster, SNDS, DMARC, complaints, ESP events, and your own MTA logs — correlated into one incident timeline with a root-cause hypothesis. Silent drops between your MTA and ESP become visible for the first time.
Beyond the modules
The modules watch. These capabilities explain and prove.
Shipped alongside the seven modules — composite scoring, evidence engines, and tenant-facing tooling, all reading the same ground-truth data.
ScoringVela Score
One composite health number per domain — reputation, placement, incidents, blocklists, SNDS, DMARC — with a per-component breakdown that shows its work.
EvidenceReplay
Per-hour MTA↔ESP reconciliation that names which receiver is silently dropping your mail — the silent-drop evidence no seed list can produce.
Pre-sendPreflight
Risk scoring before a campaign leaves: hard blockers and penalties from live blacklist, reputation, and incident state — advisory, never a gate.
ContentContent Lint
Spam-phrase, link-hygiene, and image-ratio checks on your copy before it costs you reputation — stateless, instant, API-callable.
TargetsSLOs
Deliverability SLO targets with error budgets and burn-rate alerts — know when inbox placement trends toward breaching your own bar.
Client-readyReports
White-label branded PDF reports and daily/weekly digests — your logo, your client roster, generated from the same incident and metric data.
PublicStatus pages
Share a public per-tenant status page — score, open incidents, blacklist standing — behind a revocable token link. No login required to read.
IntegrateAPI & webhooks
REST API v1 with per-tenant keys, outbound event webhooks with HMAC signatures, and CSV/JSON export of every dataset the dashboard shows.
How it works
Three steps from blind sending to a watched bridge.
Connect your stack
Point Sendvela at your MTA or ESP. Credentials are encrypted at rest with a master key; nothing leaves your infrastructure except the checks.
We read the wind
Reputation pulls, DNS authentication checks, and seed-placement probes run continuously in the background and roll up into one score.
You stay in the inbox
Trends, alerts, and warmup schedules keep small problems small. Your sending stack stays yours — Sendvela just keeps it honest.
“Email doesn't fail with an error message. It fails with a silence you mistake for apathy. Sendvela exists to end that silence.”— The Sendvela engineering log
