## EmailWebhook

EmailWebhook is a developer platform that converts Gmail and Outlook activity into structured webhook events. Rather than dealing with historyId tracking, MIME parsing and provider-specific notification formats, teams register a webhook URL and receive clean JSON payloads describing exactly what happened in a mailbox. The service handles the plumbing: watching mailboxes, normalizing messages, refreshing OAuth tokens and retrying deliveries.

The event model is intentionally granular. Developers can subscribe to inbox additions, reads, unread changes, sends, drafts, labels, spam, trash and deletion events, or use catch-all deletion handling. This makes it straightforward to build features like invoice parsing, support ticketing, contract workflows and rapid lead capture without writing provider-specific code.

Beyond inbound events, EmailWebhook offers a unified REST API for sending messages, listing mailboxes, managing labels and migrating users between Gmail and Outlook. Security features include TLS 1.3 in transit, AES-256 at rest, OAuth 2.0 without password storage, audit logging and hosting on Google Cloud Platform, with SOC 2, HIPAA and GDPR compliance noted as pending.

**Pricing & Plans:** EmailWebhook uses usage-based tiers with a permanent free plan (500 notifications/month, unlimited mailboxes). Paid plans start at $29/month for 5,000 notifications, $99/month for 50,000, and $399/month for 250,000, all with unlimited mailboxes and 30-day event retention; higher tiers add priority and 24/7 support. The first 500 emails are free and no credit card is required to start.

- **Clean JSON webhooks:** Get granular, standardized events such as inbox.added, inbox.read, sent.added, drafts.added, spam.added, label.added and catch-all deletion events for both Gmail and Outlook.
- **Zero duplicate events:** Advanced deduplication stops the same Gmail message from firing more than once, so downstream systems never process duplicates.
- **Reliable delivery and replays:** Failed deliveries are retried with exponential backoff for roughly 1.5 hours, and all events are stored for 30 days so you can replay any delivery via the API.
- **One API for Gmail and Outlook:** A single REST API sends emails, lists messages, manages labels and migrates users across Gmail and Outlook with encrypted credential storage.
- **Automatic OAuth refresh:** Gmail watches and Outlook subscriptions are automatically renewed and OAuth credentials refreshed, eliminating ongoing maintenance work.

**Strengths:** Turns Gmail and Outlook into a single normalized webhook API; Built-in deduplication and exponential-backoff retries reduce engineering effort; Unified send/list/label API avoids provider-specific code; Free tier with 500 notifications per month and no credit card

**Limitations:** Requires OAuth setup and a publicly reachable webhook endpoint on your side; Compliance certifications (SOC 2, HIPAA, GDPR) are still listed as pending; No dedicated phone support on lower tiers; Pricing scales with notification volume, which can get costly at very high throughput

## SendBridge

SendBridge is an email verification service built around one job: keeping your mailing lists free of addresses that will bounce, complain or trigger spam traps. Rather than a simple valid/invalid check, every address is categorized as Deliverable, Undeliverable, Risky or Unknown, which lets you decide whether to send, suppress or throttle a contact. The risky category is the interesting one, covering spam traps, role-based accounts, catch-all domains and disposable addresses that a naive checker would let through.

The workflow is designed to be non-technical. You create a free account, upload a list into the client area, and download the cleaned results as XLSX, CSV or TXT in the same order as your upload, ready to push into your sending platform. For teams that need verification at the point of capture, a real-time API with examples for Go, Java, PHP, Python and .NET lets you check addresses during signup or import.

SendBridge also bundles a set of free deliverability tools, including a Mail-Tester alternative that scores your sending setup out of 100 with SPF, DKIM, DMARC, rDNS and 23+ blacklist checks, plus an email validator, SPF record generator and DNS/MX lookup tools. The service is operated by CORE LABS s.r.o. in Prague, and free accounts include 100 verifications a month.

**Pricing & Plans:** Freemium. Free account includes 100 email verifications per month, plus free deliverability and DNS tools with no daily cap. Paid plans and higher-volume verification are available; check the pricing page for current tiers.

- **Deliverability Classification:** Every address is classified as Deliverable, Undeliverable, Risky or Unknown, so you know exactly why a contact should be kept, throttled or dropped.
- **Risk and Spam-Trap Detection:** Detects the address types that quietly wreck campaigns, including spam traps, role accounts, catch-all domains and disposable inboxes.
- **Bulk List Cleaning:** Upload a list in the client area and download a cleaned file in Excel XLSX, CSV or TXT while keeping your original row order.
- **Real-Time Verification API:** Verify addresses in real time on signup or import with documented examples for Go, Java, PHP, Python and .NET.
- **Free Deliverability and DNS Tools:** A free Mail-Tester style deliverability checker scores your sending setup out of 100 with SPF, DKIM, DMARC, rDNS and 23+ blacklist checks, with no daily cap.

**Strengths:** Free tier with 100 verifications per month to test accuracy; Four-way classification (Deliverable, Undeliverable, Risky, Unknown) gives actionable results; Real-time API with examples for Go, Java, PHP, Python and .NET; Free Mail-Tester alternative with unlimited tests and no account required

**Limitations:** Full pricing tiers are not shown until checkout, so larger volumes require contacting the team or pricing page; Catch-all and role-based addresses still add uncertainty even with high claimed accuracy; No native integrations ecosystem highlighted beyond the API
