## Email Verifier

Email Verifier is a browser-based tool from emailverifier.ai that answers a simple question: will this address actually accept your message? Rather than relying on cached or heuristically guessed results, it connects to the receiving mail server in real time and reports what it finds, usually in under a second. You paste an address, hit verify, and get a clear verdict plus a breakdown of each individual check.

The verification pipeline runs across seven layers. Syntax validation confirms the address follows RFC 5322 before any network call. MX record lookup confirms the domain is configured to receive mail. SMTP validation then probes the mailbox to see whether it is active. On top of that, catch-all detection flags domains that accept every message regardless of mailbox existence, disposable email detection identifies throwaway inbox providers, and role address flagging points out shared inboxes such as info@ or support@ that tend to have low engagement. Anything not clearly deliverable is marked Risky rather than lumped in with hard failures.

The product is aimed at anyone whose sender reputation depends on list quality: email marketers cleaning subscriber lists, sales teams validating leads, developers adding real-time checks to signup forms, recruiters confirming contacts, SaaS teams reducing fake registrations and e-commerce teams keeping customer databases accurate. Single checks are free to start with no account or credit card required, while bulk list verification and API access are unlocked on paid plans. It works entirely online with nothing to install.

**Pricing & Plans:** Freemium. Several single-address checks per day are free without an account. Bulk verification and higher volumes with API access require a paid plan; exact tier pricing is shown in the app.

- **Real-time SMTP validation:** Connects to the receiving mail server to confirm the mailbox is active and accepting messages, instead of relying on cached results.
- **Seven-layer check pipeline:** Syntax, MX records, SMTP, catch-all detection, disposable detection and role-address flagging combine into one verdict.
- **Clear three-way verdict:** Every address is labelled Deliverable, Risky or Undeliverable with a per-check breakdown so you know why.
- **Bulk list verification:** Upload and clean whole lists rather than checking addresses one at a time, available on paid plans.
- **API and signup-form integration:** Developers can embed real-time verification to block throwaway and dead addresses at the point of capture.

**Strengths:** Free daily single-address checks with no account or card required; Real-time SMTP checks rather than cached guesses; Explains the verdict with a per-check breakdown; Covers catch-all, disposable and role addresses that simpler tools ignore

**Limitations:** Bulk list verification and API access sit behind paid plans; Catch-all domains are still reported as risky rather than definitively valid or invalid; Results depend on receiving servers answering probes, which not all do

## 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
