QuickEmailVerification pricing for basic email validation limits your growth potential. 1Lookup delivers multi-service validation with a fraud score on every lookup. As the leading QuickEmailVerification alternative, we offer phone + email + IP validation in one modern platform with advanced fraud detection.
Two ways to verify email
QuickEmailVerification focuses on email deliverability. 1Lookup validates email, phone, and IP through one API.
The 1Lookup approach
- Real-time email checks: syntax, domain, MX, SMTP, catch-all, disposable, and role-based
- A deliverability read and a fraud score on every address
- The same API key also validates phone numbers and IP addresses
- One real-time endpoint plus bulk list cleaning, drawn from one credit balance
- Data checked in real time, identical lookups cached for 7 days
- Live in about 5 minutes, with 1,000 requests/min included
The QuickEmailVerification approach
- Email verification via real-time API and bulk uploads
- Deliverability and catch-all detection
- Credit-based email pricing
- Email-only, no phone or IP validation
- Well-suited to list hygiene
QuickEmailVerification is a capable email checker. If you also need phone and IP validation with a fraud score, 1Lookup does all three on one key.
Good tool, no fluff
Been using 1Lookup for a couple months now. We verify leads before pushing them into Pipedrive. Honestly it just works. Not fancy, not buggy, and the support actually answers when you write them. Can't really ask for more.
Brian LetzterUnited States · October 2025The most practical data tool I've used
I've seen hundreds of validation APIs come and go. 1Lookup stands out because they don't oversell. Their data is solid, support is honest, and they're transparent about limitations, which is rare in this industry. I've replaced three tools with this one. They listen, they iterate, and they keep improving. You can feel there are actual engineers behind it, not just salespeople.
Bùi Thị Thanh NgọcVietnam · October 2025Solid phone validation API
We use 1Lookup inside our telemarketing app to verify numbers before they go to the dialer. Setup was simple and the results have been consistent. It's not overloaded with features, just fast, accurate, and reliable. Docs could be a bit deeper, but honestly, it works out of the box.
Dirk van MeerUnited States · December 2025Saved us from hundreds of spam signups
We run a SaaS product with free trials and were getting flooded with bots and fake users. After integrating 1Lookup, the difference was night and day. It quietly filters out junk signups without blocking legitimate customers. The support team even helped us fine-tune our risk thresholds on a quick Zoom call. Being honest, we couldn't ask for more.
Ido ShachamUnited States · January 2026A good addition to our workflow
1Lookup has been a good addition to our workflow over the last few months. We use it to verify IPs, emails, and phone numbers, which has noticeably cut down the time we spend chasing dead-end applications. It's reasonably priced and their support team is actually helpful. It's a very practical tool for what we need.

QuickEmailVerification vs 1Lookup FAQ
Common questions about QuickEmailVerification and switching to 1Lookup
What is QuickEmailVerification?
QuickEmailVerification is an email verification service that checks whether email addresses are valid and deliverable before you send to them. It cleans mailing lists by flagging invalid, disposable, role-based, and catch-all addresses, and offers both bulk list validation and a real-time API with integrations for common email platforms. Its focus is email hygiene rather than phone or IP data.
How much does QuickEmailVerification cost?
QuickEmailVerification uses a credit-based model with two options: pay-as-you-go persistent credits that never expire, and monthly per-day subscription plans. As of publication, persistent credits start at roughly $4 for 500 verifications, monthly subscriptions start around $25 per month, and the effective per-email rate drops at higher volumes. It also offers a free daily credit allowance for testing, but because pricing can change, check QuickEmailVerification’s official pricing page for current figures.
What is the best QuickEmailVerification alternative?
The best alternative depends on what you need to verify. If you only clean email lists, QuickEmailVerification is a capable, affordable choice; if you also validate phone numbers and IP addresses, 1Lookup is a strong QuickEmailVerification alternative because it handles email, phone, and IP through one API and one universal credit balance. Teams consolidating several verification vendors often pick 1Lookup to avoid juggling separate tools and credit pools.
How is 1Lookup different from QuickEmailVerification?
QuickEmailVerification specializes in email verification only, while 1Lookup is a broader data-verification API that validates phone numbers, emails, and IP addresses through a single API and one universal credit system. 1Lookup refreshes its data daily from FCC and carrier sources and returns a fraud score on every lookup, and it also offers carrier/HLR lookup, reverse lookup, and IP fraud intelligence. Both handle email validation well; 1Lookup’s edge is unifying phone, email, and IP checks in one platform.
Can I try 1Lookup for free?
Yes. 1Lookup offers a 7-day free trial so you can test email, phone, and IP validation before you commit. The same universal credit system applies across every lookup type, so your trial credits work for whatever you need to verify, and you can sign up and start validating without contacting sales first.
The Complete QuickEmailVerification Alternative
Why settle for basic email-only validation? Move to 1Lookup for phone, email, and IP validation with a fraud score on every lookup.

Before you sign: QuickEmailVerification and 1Lookup on the operational terms
The terms that decide what a year actually costs, rather than what the first month does. A blank means we could not verify it on either product’s published pages, not that the answer is nothing.
| Term | 1Lookup | QuickEmailVerification |
|---|---|---|
| Minimum commitment | None. Monthly plans with no contract and no minimum volume; cancel any time | No contract. 'No contracts, no hidden charges, no setup fees. There is no long-term commitment and you can cancel your subscription at any time.' Enterprise is aimed at 'teams verifying 500K+ emails/month' and is quote-only. |
| Going over your quota | — | Pay-as-you-go stops rather than overcharging: 'You won't be charged automatically when your credits are finished.' Subscription credits are a daily allowance that resets each day. No overage rate published. |
| API access | Included on every plan and during the free trial; there is no tier that unlocks it | API is available on every tier including the free 100 credits/day tier; there is no separate API plan. API keys can be restricted to allowed IP addresses or CIDR ranges. |
| Rate limit | 1,000 requests per minute on standard accounts, with higher limits available on request | No numeric rate limit published. The API docs list HTTP '429 - Too many requests. Rate limit exceeded.' as an error code without stating the threshold. The enterprise page says enterprise accounts get 'higher API rate limits' configured to throughput needs. |
| Uptime SLA | — | Uptime SLA is an Enterprise-only item: 'Enterprise plans include uptime SLA commitments tailored to your needs.' No percentage is published. |
| Compliance | — | ISO 27001 Certified, GDPR Compliant, CCPA Compliant and HIPAA Compliant (badges on the enterprise page); DPA available, plus custom NDA and MSA on enterprise. |
| Support | Starter: Email Support; Growth: Priority Email & Chat Support; Professional: Chat + Live Meeting; Enterprise: Dedicated CSM | A web contact form at https://quickemailverification.com/contact-us (note /contact 404s) is the only standard-plan support channel published; no support email address or phone number is listed anywhere on the site. The plans page promises 'Personalized Support' on paid plans without defining it. Enterprise adds a dedicated account manager with 'Priority access, faster response times, direct communication', technical onboarding, and free deliverability consulting. Enterprise enquiries are answered 'within 24 hours'. |
QuickEmailVerification fine print worth reading twice
Published terms that change what QuickEmailVerification costs or what you can do with it. Each one links to the QuickEmailVerification page it was read on, because a claim about somebody else’s contract should be checkable in one click.
Monthly subscription plans buy a per-day credit allowance that resets daily ('Credit resets daily'), so unused daily credits do not accumulate; only the one-time Persistent Credits plan carries credits forward.

What you actually work in
QuickEmailVerification is a a dashboard screenshot with an Upload Email List / Buy Credits / account toolbar, tiles for 'Persistent Credits — No time limit / No Expiry' and 'Per Day Credits — This will be reset daily' and a lifetime verified count, a Verification Activity line chart with Last 24 Hours / 7 Days / 30 Days / 12 Months toggles, and a valid-versus-invalid Breakdown donut chart product you log into. 1Lookup is an API and a dashboard you mostly do not log into: you call it from the system that already has the record. Which of those you want is usually the whole decision, so here is theirs.
