DeBounce is a fast, accurate, and affordable email validation service. It helps businesses to get rid of invalid email addresses from their databases. If you use popular ESPs to send emails, DeBounce can easily integrate with them and transfer your lists for validation. Here are some key features of DeBounce:
Besides the paid services, DeBounce offers some free services. It offers a life-time free disposable email detection API that helps you combat fake and temporary signups. However, if you want to have a more complex validation engine, you can go for a paid plan. DeBounce has more than 900 positive reviews which show the customers are satisfied and the team really cares about each customer.
BounceZero verifies email addresses in real time using a 5-stage pipeline: syntax check, DNS/MX lookup, SMTP handshake, catch-all detection, and ML scoring across 65+ signals.
Every email returns one of four verdicts: Deliverable, Risky, Undeliverable, or Unknown โ with a confidence score and explanation.

BounceZero's answer:
BounceZero runs a true 5-stage verification pipeline โ syntax, DNS/MX, live SMTP handshake, catch-all detection, and ML scoring โ on every address. Most competitors stop at SMTP. We go further with a 3-probe catch-all test, XGBoost risk scoring for providers that block SMTP probes, and per-provider intelligence built from 200+ email provider profiles including every major ISP in Europe, the US, and Latin America.
BounceZero's answer:
Python (FastAPI) for the verification engine and API, PostgreSQL for data storage, XGBoost and Bayesian models for ML scoring, SMTP probing across dedicated IP pools for deliverability testing, and a PHP frontend. Hosted on OVH infrastructure with BYOIP egress for clean sending reputation.
BounceZero's answer:
Three reasons: accuracy, transparency, and price. BounceZero returns a confidence score and plain-English explanation with every result โ not just a pass/fail verdict. It costs $3 per 1,000 verifications with no subscription required and 100 free credits every month. And the API returns results in under 3 seconds with no rate limits on paid plans.
BounceZero's answer:
Email marketers, growth teams, and developers who send campaigns or build signup flows and need to keep bounce rates below 2%. Also agencies cleaning client lists before migrations and SaaS companies validating email at the point of collection via API.
BounceZero's answer:
BounceZero was built after seeing too many email campaigns destroyed by high bounce rates that could have been prevented. Existing tools were either expensive subscription products or black-box APIs that gave a verdict with no explanation. We built BounceZero to be affordable, transparent, and accurate โ starting with 100 free credits so anyone can test it without a credit card.

Have you run your list through a list cleaner/deliverability solution? I use debounce's API (debounce.io) for our product and it is pretty good. Source: about 5 years ago
I use a list taken from GitHub but we also use an API to check if itโs a disposable inbox (https://debounce.io/). Source: about 5 years ago
