Disposable email providers
Domain name typo corrections
Our 12 stage comprehensive
List cleaning process
We get rid of all the duplicate email addresses on your mailing list. This allows your list to contain only unique addresses and thereby reduce your unsubscription rate significantly.
We run a thorough scan of all the domains on your mailing list. We scan them and classify them as being parked/invalid/non-working domains. This helps in optimizing your open rates.
Each email address on your list is scanned against our spam trap indicators that we derived from online providers DBs. Its the most comprehensive method to avoid getting your IP’s blacklisted.
All email addresses on your mailing list is scanned for a match against our gigantic complainers database. If a match is found, that email will be automatically set aside to inform you about the risk.
Our system scans across millions of email addresses and knows quite well what are deemed high-risk keywords in an email and high-risk TLDs. It will intelligently separate these out for your benefit.
Any email address with invalid syntax is automatically taken care of. You don’t need to worry about our system skipping these addresses. It will accurately determine what is an email address and what isn’t.
Our scan goes much deeper than just email address. Each email address is checked for its MX records validity. All non-working and invalid MX records are efficiently dealt with.
8] Suppressed email
Do you have a collection of email addresses that have been deemed unsafe or invalid or have complained before? We can make sure your new list doesn’t contain these email addresses.
9] Unbalanced delimiter
Our system is intelligent enough to identify email addresses containing out of balance delimiters. Our algorithm is complex enough to find these records with unbalanced delimiters.
10] Mailbox error
With real-time responses from MTA, we can easily classify and segment email addresses outputting various mailbox errors including messages like “Mailbox full” (classified as soft bounce).
11] Custom TLDs
Do you have specific custom TLD’s that you want out of your mailing list. We can make it happen. Our system is advanced enough to identify and pick out those TLD’s that are unwanted.
12] SEVL score
Score is allotted by our system which shows the quality of your mailing list and it’s emails. Just because the email address is valid doesn’t mean it’s a good email to send to.
We use processes that may take time but we never compromise on the accuracy of our results.

Email validation APIs
Single email validation API
We have created a simple name spaced API that provides complete control over your email validation process. All of the functionality that you find in our control panel will be made available via our API. We support all of the major validation actions and selections, allowing you to develop robust applications and integrations. With the single email validation API, you can verify a single email address at a time with ease. Use it to verify your customer data or integrate it into your existing apps or third-party services you use. We have options available to scan for spam traps, complainers, syntax issues, and more.
Form validation API
Form validation API allows you to quickly and efficiently verify the information your customers have provided you on your contact forms, sign up forms, and other web forms. This API allows you to launch a large number of concurrent requests and receive responses within milliseconds so your customers can continue with their online signup/activity. We return a large number of useful responses like whether the particular email address belongs to a free email service provider, if it has any typos, or if it is a role-based address, and more.
Bulk email validation API
Batch processing API is ideal for companies who want to verify and validate their mailing lists without having to access our control panel. You can programmatically connect the services and third-party apps to send to our system your mailing lists to be verified. Our system can process ten files at a time and takes them in a CSV format. Upload, monitor, and download verified contact lists all through the bulk email validation API. Just like the other APIs, we allow scanning for emails from free service providers, disposable email service providers, role-based emails, bad addresses, and more.
Frequently asked questions
Over the years, we have developed a set of processes that help us determine the existence of an email address. Our system is programmed to carry out email validation in two sub-processes – pre-validation and post-validation. Pre-validations are steps taken before the actual validation begins. They include things like deduplication, spam-trap scan, complainers scan, risk checks, syntax checks, suppressed email removal, and unbalanced delimiters. Following from there, the post-validation kicks in. It involves domain checks, MTA checks, Mailbox Error checks, Custom TLD checks, and EV score allocation.
Email address validationWhile email address validation deals with the actual existence of whether an email address exists or not, this process validates those that have been verified. The difference might seem little but they are completely separate processes run during both parts of the email validation process. One part of it is to validate email and the related domain’s existence while the other part concentrates on things like the risk involved with keywords within the email, high risky domains, suppressed email removal, complainers removal, spam trap email address removal, and custom TLD separation.
Spamtraps (aka honeypots) are emails that are created solely to lure spammers in. In email marketing terms, it’s a bait that you may fall victim to if you are collecting email addresses from sources and emailing without their permission. We have a large database of these spam-trap email addresses which help us derive spam-trap indicators that we use to validate your mailing list against. If we detect any of your email addresses matching our indicators, we will automatically mark that email address helping you to stay far from these traps. When you end up sending an email to one of these email addresses, your IP is recorded and you will be blocked from sending any further emails to that ISP, or quite simply, they will place all emails coming from you in the spam folder (away from user’s inbox).
Complainer’s email address quite literally means email addresses that have been known to complaining in the past in regards to receiving bulk emails from people. These are people who have exclusively listed their email addresses to opt-out of any unsolicited bulk emails. These users are recorded as being generally reluctant to receive any advertising or promotional material. We have a large number of sources where we obtain this information from and therefore help you in achieving lower spam complaints. These users don’t want to receive any sort of bulk emails and therefore it’s best not to send them any. By avoiding sending emails to these users would mean better deliverability rates for your email campaigns.
We run several checks against each email address you provide to us. These include domain validation, risk validator, syntax verifier, mta validation, unbalanced delimiter check, and mailbox error check. Domain validation tries to eliminate email addresses that are associated with dead domains (AKA non-existent domains). This removes a majority of email addresses, which have never been registered or have been registered before but now in an expired state. Risk validator measures the risk associated with particular keywords and domains. Think of it as a scale whereby our system tries to measure the possibilities of it being non-existent against it being existent. Syntax verifier is a module within the validation process that enables email addresses without proper syntax to be automatically removed. In general, all email addresses have a standard that they must adhere to. Failure to adhere is likely to causes errors and therefore likely to be non-existent. MTA stands for Mail Transfer Agent or Mail Relay. It’s software that transfers emails from one computer to another. If there is no MTA available or no response from one, likely, no email addresses passing through it would work. An unbalanced delimiter check relies on a similar principle as that of a syntax check but is more complicated in design. In simple terms, it tries to find any ‘outliers’ in the way email address looks and marks it with appropriate status. Mailbox error check is when sets of messages are exchanged between our verification programs to that of the email service provider causing errors while intending to transfer mail. This is also another sign of the email address being invalid.
We offer a couple of options for our users to customize their email validation job. Not just do they include the option to validate against our spam-trap indicators and complainers but they also can utilize suppressed emails, deduplication, custom TLDs, and EV score processing features. If you have a set of users who have explicitly asked you not to email them, simply upload that list to our control panel and we will make sure they are not included in any of the email validation jobs you launch. This helps you keep away from complaints from unwanted emails from your company. You also can choose where you would like the duplicate email addresses to be removed or kept in the list as they are. Another neat feature is the ability to automatically get rid of custom top-level domains. Don’t want any “.co.uk” email addresses in the list? No problem, we can get those email addresses kept aside upon your request.
Over the years, our email validation technology has become far more advanced since the time we started. We’ve developed a system that uses a lot of artificial intelligence techniques. Every job improves our validation processes and methods for the next one. Combine this with our live feeds from various sources, our system becomes an ultimate choice for validating your email addresses. Each job goes through pre and post validation stage to ensure accuracy for maximum marketing results.
Our live feeds are updated daily with newer records added constantly and our AI models are trained with better spam traps indicators and complainers. We get these feeds from various sources and its what gives us a technical advantage over our competitors. This helps us achieve great results by removing those unwanted email addresses that could potentially harm your reputation as an email sender and thereby affecting your future communications with your customers.
We have created a simple API for all our customers to be able to integrate it right into their platforms or systems. We have customers who implemented it for form validation, CRM system, and sign up process just to name a few. This allows you to completely customize the validation experience. You choose how you’d like our system to clean your mailing lists. The possibilities are endless – start developing robust applications and integrations now.
Our email validation API allows developers to integrate email data validation capabilities into 3rd-party applications. Spotzee email validation connects with email domains to validate the status of email addresses and removes email addresses containing invalid domains. It can also remove duplicate email addresses, suggests correct domain names (typo suggestion), clean records that match our spam-trap indicators, checks for high-risk keywords/domains, remove email addresses containing invalid syntax, and more. We also have a bulk email validation API and form validation API available for use.
We use multiple tier-1 network transit providers at each facility and all connections are 10 Gig-E to ensure redundancy and capacity. We only use the most trusted data center providers who have redundant power, onsite diesel generators and battery backups, physical security, and multiple network transit paths to perform all your mailing list cleaning jobs.
An email address although perfectly valid in terms of sending an email to, often involves validation against spam traps, complainers, and suppressed email addresses. It won’t end here – some advanced email list cleaning software also analyze for high risk keywords and domains, separate according to TLD’s you want to email to, and look out for actual bounces that are likely to occur if SMTP response wasn’t good enough to determine an email address validity.
We often have our email marketing customers ask this and we answer in this typical way. It purely depends on your business needs and your objectives. It can be done in three ways.
1) In real-time – Using our email validation API, you can have your form validated right at the point of entry. This includes support for websites, forum, registration forms, signup forms, leads forms, mobile forms, and any other forms you can think of. Using our API gives you that advantage of letting your customers know they have incorrectly entered their email address. After all, a wrong address means a sale lost (if you are only collecting their emails to get started, like a lot of businesses do). If you choose an API, against all the other things listed, it would prove useful to you and your business.
2) In batch processing – Most of our customers tend to use our batch-processing facility. This is because it gives you the convenience of uploading to our control panel and letting you download when your mailing list has been verified. Its often the simplest way to get started with email address validation. It reduces the technicality involved with implementing an API. The timing of it depends on the number of email addresses we have to validate. This maybe good for companies who have smaller databases and are not frequent mailers.
3) By automation – We have a number of ways you can use and we are continuously looking out for more ways to make it easy to carry out email address validation. You will be able to use FTP, Remote Database, Dropbox and much more to validate automatically after a set period of time. This allows you to have your email data validated so you can always have the clean mailing list ready to use for your email marketing campaigns.
No problem! Just give us shout out through our contact page. We offer our customers a number of ways to get in touch with us and our friendly staff will gladly answer any questions you may have.
