SendBridge
ClaimSendBridge is an email verification and list-cleaning tool to reduce bounces and improve deliverability. Supports bulk uploads, a real-time API, and a free single-address validator.
Overview
SendBridge is an email verification and list-cleaning product for reducing bounces, protecting sender reputation, and improving the chance that messages reach inboxes. It combines bulk list processing, a real-time verification API, and a free single-address validator.
The service describes its verification process as running more than 21 checks and classifying results into practical outcome groups. Users can upload lists in the client area, verify emails as they are collected through the API, or test an individual address with the free tool.
Features
Real-time API validation
Check emails as they are collected with a real-time API designed for form and application workflows.
Categorized verification reports
Results are grouped into Deliverable, Undeliverable, Risky, or Unknown so teams can review outcomes at a glance.
Structured API output
The API example shows a lightweight JSON response with checks such as syntax, disposable status, MX validity, and score.
Exportable cleaned lists
Cleaned lists can be downloaded in XLSX, CSV, or TXT formats and kept in the same order as the upload.
Free single-address validator
The free validator checks an entered address in real time without sending an email and shows whether the mailbox exists and can receive messages.
Use Cases
Prepare bulk campaign lists
Clean imported marketing lists before a campaign by uploading addresses, reviewing the verification results, and exporting a corrected file.
Verify emails at point of entry
Validate addresses during signup or form submission so invalid or disposable emails are filtered before they enter the database.
Check a single address
Use the free validator to test one address quickly when you want a manual check without sending a message.
Automate validation in product workflows
Integrate the API into an app or backend workflow so each new email gets checked in real time and only valid addresses are stored.
Inspect list quality signals
Review deliverability-related checks such as syntax, MX records, disposable status, and scoring when investigating why a contact list may perform poorly.
