The verifier that doesn't give up on catch-alls

Most tools stop at SMTP and mark half your list "risky." We go deeper — so you keep the addresses that actually deliver.

Catch All Verifier

We probe greylisting, accept-all behavior, and provider signals to estimate real deliverability — turning "risky" guesses into confident verdicts.

Real-time API

Validate at the signup form with a configurable timeout. JSON in, JSON out.

Bulk at scale

Upload up to 500k rows. Auto column detection, pause & resume.

0–100 score

Every address gets a deliverability score, not just pass/fail.

Disposable & role filter

Block throwaway and shared inboxes before they hit your DB.

See what dirty data costs you

Estimate the bounces you'd avoid — and the sender reputation you'd protect — by cleaning before you send.

Questions, answered

Everything you need to know before you start verifying.

We verify at 99%+ accuracy and go a step further than most tools by resolving catch-all domains to a real deliverability verdict instead of just flagging them "risky."

A catch-all domain accepts mail to any address, so most verifiers can't confirm a specific mailbox. BounceZip probes further to estimate whether the address actually delivers.

Never. Credits roll over indefinitely and stay in your account until you use them — no subscription, no monthly reset.

Yes — every account starts with 100 free credits, no credit card required. Buy more only when you need them.

Absolutely. Our REST API returns a full verdict and supports a configurable 2–60 second timeout for your signup workflow.

One standard email verification uses 1 credit. Catch-all deep verification uses 5 credits, since it takes more work to estimate real deliverability. You only spend credits on emails actually verified — paused or skipped rows aren't charged.

Yes — unused credit packs can be refunded within 30 days of purchase. Just email support@bouncezip.com and we'll sort it out within 24 hours.

Catch-all domains accept any address, so most tools give up and flag the whole list. BounceZip probes deeper to tell you which catch-all addresses actually deliver — so you keep real contacts instead of deleting them.

Accept-all detection

We identify domains that accept every address so a normal SMTP check can't confirm a mailbox.

Deeper probing

Greylisting handling and provider-specific signals push past the "accept-all" wall.

A real verdict

Each catch-all address gets a 0–100 score and a clear send / caution / skip recommendation.

Don't delete deliverable contacts

Flagging every catch-all as "risky" quietly throws away real, reachable people. We help you keep them.

Built by email marketers,
for email marketers

We got tired of watching good campaigns die in spam folders because of dirty lists. So we built the verifier we always wanted.

BounceZip started in 2023 when our founders — a growth marketer and a backend engineer — kept hitting the same wall: every tool flagged catch-all domains as "risky" and left them guessing. Half their list was unusable, not because it was bad, but because the tools gave up too early.

So we built verification that goes deeper. Today, BounceZip checks six layers on every address, resolves catch-all domains to a real verdict, and powers everything from a single dashboard check to billions of API calls — with transparent, credits-never-expire pricing.

Accuracy first

Six layers of checks and real catch-all resolution. We'd rather be right than fast — and we're both.

Transparent pricing

Credits never expire, no surprise overages, and a free tier that's genuinely useful.

Developer-friendly

A clean REST API, honest docs, and responses fast enough to run inline at signup.

Introduction

The world is changing rapidly, and technology has become an essential part of our daily lives.

As a result, digital skills are no longer optional—they are necessary for personal and professional growth.

Whether you are a student, job seeker, freelancer, or business owner, developing digital skills can help you stay competitive and discover new opportunities.

What Are Digital Skills?

Digital skills are the abilities required to use digital devices, software, online platforms, and technology effectively. These skills range from basic computer knowledge and internet browsing to advanced areas such as digital marketing, graphic design, programming, and data analysis.

Some valuable digital skills include:

  • Computer and internet proficiency

  • Digital marketing and social media management

  • Graphic design and content creation

  • Website development and programming

  • Data analysis and online collaboration

Why Are Digital Skills Important?

1. Better Career Opportunities

Employers increasingly look for candidates who can work with modern digital tools. Having relevant digital skills can help you qualify for more positions and stand out in a competitive job market.

2. Opportunities for Freelancing

Digital skills can open doors to remote work and freelancing. Platforms and online networks allow skilled professionals to connect with clients worldwide and earn income by providing valuable services.

3. Improved Productivity

Knowing how to use digital tools helps you complete tasks more efficiently. From managing projects to automating repetitive work, technology can save time and improve the quality of your work.

4. Support for Business Growth

Businesses can use digital marketing, websites, analytics, and online communication tools to reach more customers, improve their services, and build stronger relationships with their audiences.

How to Develop Your Digital Skills

Start learning today and invest in a more successful digital future.

Privacy Policy

Last updated: June 2026
This summary is written in plain language so you can actually read it. BounceZip is built privacy-first — we process email data to verify it, and nothing more.

1. What we collect

We collect the information you give us to run your account and verifications:

  • Account data — your name, email, company, and password (hashed).
  • Verification data — the email addresses you submit for verification, and the results we return.
  • Billing data — handled by our payment processor; we never store full card numbers.
  • Usage data — basic logs and analytics to keep the service secure and reliable.

2. How we use it

We use your data only to provide and improve BounceZip: verifying the emails you submit, maintaining your account and credits, processing payments, and sending essential service messages. We do not sell your data, and we never use the email addresses you verify for our own marketing.

3. Data retention

Verification lists are retained only as long as needed to deliver your results, and you can delete them at any time from your dashboard. Account and billing records are kept for as long as your account is active and as required by law.

4. Sharing

We share data only with trusted sub-processors (hosting, payments, email delivery) under strict data-processing agreements — never with advertisers or data brokers.

5. Your rights

You can access, export, correct, or delete your data at any time. Email privacy@bouncezip.com and we'll respond within 30 days.

6. Contact

Questions about this policy? Reach us at privacy@bouncezip.com.

Last updated: June 2026
By creating an account or using BounceZip, you agree to these terms. Please read them.

1. Your account

You're responsible for keeping your login credentials and API keys secure, and for all activity under your account. You must be at least 18 and provide accurate information.

2. Acceptable use

You agree to verify only email addresses you have a lawful basis to process. You may not use BounceZip to send spam, harvest addresses unlawfully, or attempt to disrupt or reverse-engineer the service.

3. Credits & payment

  • One standard verification uses 1 credit; catch-all checks use 5 credits.
  • Credits are prepaid, never expire, and are only consumed on emails actually verified.
  • Unused credit packs can be refunded within 30 days of purchase.

4. Service availability

We target 99.9% uptime and back it with an SLA on paid plans, but the service is provided "as is." Verification results are best-effort estimates of deliverability, not a guarantee that any message will be delivered.

5. Termination

You can close your account anytime. We may suspend accounts that violate these terms. On termination, unused paid credits remain refundable per section 3.

6. Liability

To the extent permitted by law, BounceZip's total liability is limited to the amount you paid us in the preceding 12 months.

7. Contact

Questions about these terms? Email legal@bouncezip.com.

Last updated: June 2026
BounceZip is built to help you stay GDPR-compliant when verifying the personal data of EU/EEA residents.

1. Roles

For the email addresses you upload, you are the data controller and BounceZip is the data processor — we process that data solely on your instructions to perform verification.

2. Lawful basis

You're responsible for having a lawful basis (such as legitimate interest or consent) to process and verify the addresses you submit. Verification itself supports data accuracy — a core GDPR principle.

3. Data Processing Agreement

We offer a DPA to all customers covering processing scope, sub-processors, security measures, and breach notification. Request one at dpa@bouncezip.com.

4. Data location & transfers

Data is processed on EU-compliant infrastructure, with Standard Contractual Clauses in place for any transfers outside the EEA.

5. Security & deletion

  • Encryption in transit and at rest.
  • Verification lists deletable on demand and auto-purged after processing.
  • Strict access controls and audit logging.

6. Data-subject requests

We support access, rectification, erasure, and portability requests. Contact privacy@bouncezip.com and we'll assist within statutory timeframes.
