Email marketers know the costs involved, and the effort put into sending an email campaign.

Well, a whole lot of things – See our email scrubbing process. Most of the preliminary steps we perform are to do with the format/syntax of an email address, domain validity and if the user/mailbox really exists. Of course, once we determine all these, there are a lot more things we look at. These include if those email addresses match with any complainers we have on file or spam trap email address. We also look into high-risk keywords and domains. Later on in the process, we look into unbalanced delimiters within an email address; any suppressed emails that you uploaded.

Yes. We are capable of validating email in large quantities. We have customers who have had their mailing lists validated consisting of millions of email addresses. Our system intelligently routes emails into various scaling servers and performs above checks and then put them back together (much like a surgery). So if you tried to validate email one by one, our bulk email verifier can solve your problems. Our spotzee email verifier app takes the bulk of it and helps in massive reduction of bounce backs and thereby improving your bounce rate. Your email service providers would be in a good place and so will you. This is because you will be getting a higher return on every penny you spend on your email marketing campaigns.

As you progress as an email marketer, you will start to realize that your mailing list is starting to accumulate invalid and non-working email addresses. Email address validation is therefore crucial to get rid of these kinds of email addresses before they start hurting your credibility as a trusted sender. Using our app, you can easily remove bounced emails, emails with invalid inboxes, unbalanced delimiter issues, syntax issues and those with high-risk keywords or domains.

The very reason our software was developed is to help customers filter through their mailing lists and be able to collect accurate email data they can use to send their marketing campaigns. Many people assume that email address validation deals with only have an ‘@’ symbol and ‘.’ somewhere in the email with an ending top-level domain like ‘com’ or ‘org’. While this is true, there is a lot more to that than such a simple syntax. Its defined by the internet standards document RFC 5322, which highlights the proper syntax of how, an email address should be.

HOW DO EMAIL ADDRESS VALIDATION SOFTWARE DEAL WITH SYNTAX ISSUE? Most programs out there deal with this in different ways. Some actually code their programs to validate email according to the standard – RFC 5322 whilst others depend purely on guesswork to validate their customer data – the same kind of guess we used just now to showcase how an email address is structured. So our advice to you is not to depend on programs that depend solely on these simple methods but to look for a program or service likes our which goes well beyond the simple structure of an email to validate its existence.

In short, no! The reason is quite simple. Email validation is a complex process and most of these free tools available on the market are free. This means they don’t have a lot of investment to invest on good engineers who can deliver results. Most of them do simple checks such as existence of ‘@’ symbol or correct TLD’s. Often times, the authors for these free tools do not understand the RFC email format rules and even if they know, they find it quite complex to code it into a system due to the number of parameters they have to keep watch on.

Ultimately, these email syntax issues can easily sneak in if visitors mistype their email addresses and domain names are usually misspelled. Use an email validation tool, which has proven itself over the years and has a solid track record with good customer base that are happy with them. A nice piece of advice, stay far from desktop programs, as they are likely to get your IP blocked and validate with very low accuracy. Also, make sure the program you are using has comprehensive email validation processes. Please check our process to get a good idea and why not try us out first?

AOL, Gmail, Hotmail, and other Internet Service Providers (ISP) are actively filtering millions of emails they receive each day on day-to-day basis. To scan through so many millions of emails they receive, it’s an increasingly difficult task for them so they rely on something called a ‘sender’s reputation’. This determines basically who gets in and who doesn’t. Return-path (a reputable email company) reports that nearly 77% of the time, it’s the delivery problems that degrade sender’s reputation score. Validate email for bounces, complainers, and spam traps; without it, your emails are likely to end up in junk folder. This is why its is recommended to our software to help you get rid of undeliverable emails.

Services like ours initially identifies all the list of undeliverable email addresses and then most services go on to validate for other things such as spam trap (aka honey pots) and complainers. A service like ours would benefit you by providing vast number of benefits. These benefits span from reduction in bounces, fewer complaints, and lower emails to spam trap email addresses, increased delivery rate to inboxes, lower costs, fewer fake addresses, and most of all increased bottom-line coming from more accurate leads. Once a list has been validated, large companies usually report a massive reduction in bounces of up to 98% and increased bottom-line that very year.

Our service scans against a large number of things before it marks an address being either valid or invalid. Our process includes things like catching any syntax errors or unbalanced delimiters, making sure the domains and MTA are responding as they should, validating if an inbox actually exists under that name, removing any previous complainers or spam trap addresses, getting rid of high risk keywords and domain names, eliminating service-role emails and much more. For a comprehensive list of things, our service scans against, you can have a look into our innovative email validation process.

There are a couple of hints that we can give you to keep your mailing list sparkling clean. Here are some of times we recommend you to use our service.

1) At data collection point – Validate email address right at the start. It will not only prevent you from sending unwanted email to wrong addresses but also help you in keeping your list clean right from the start. Use our email validation api to validate email entered by your customer. It will give them an immediate result that they have entered an invalid email and thereby prevent them from submitting the form. Our API is powerful to scan for syntax issues, unbalanced delimiters, domain checks, mta checks, suppression email removal, role-based email, typo suggestions and for bogus accounts.

2) Just before you start your marketing campaign – We highly recommend you to validate email right before you start mailing your email campaign. Those hard worked hours will not go to waste if you know that what you’re sending is actually going to reach your recipients. If you haven’t used this mailing list for more than a couple of months, list scrubbing would greatly increase your chances of getting it into the inbox rather than as a junk mail which almost no one gets to see. For larger or older mailing lists, we cannot recommend this enough. It will be very ineffective email campaign if all of your emails end up in folders other than inbox.

3) As a regular list hygiene practice – Once you know your mailing list is clean enough, what most email marketers are not aware of is the fact that it will not stay the same always. Just like you need to take shower every day, all the emails are bound to become invalid over time. There are a number of people who constantly change their providers and thereby leave their old email addresses unchecked. Constantly checking for invalid emails would help you keep your list in optimal email-ready condition. It will also help you chase up customers for whom you don’t have correct details for.
