How To Do Email List Verification (The Cheap But Effective Way)

One of the problems when it comes to using mass emailing service is that allows you to send mass emails, which can lead to bounces.

The average email bounce rate, including both hard and soft bounces, across industries is 0.7%, according to a 2020 Email Marketing benchmark study by Campaign Monitor.

When it comes to bounces, there are two types to look for, and we’re not talking about a bounce rate of a website, we’re talking bounces of emails.

The two types, a soft bounce and a hard bounce.

It’s not just an issue with the service you’re using, as you know, it also impacts sender reputation and it’s necessary to stay on top of the main issues causing a drop in sender reputation.

What is a Soft Bounce?

A soft bounce is a bounced email that isn’t permanent.

Usually a soft bounce has to do with a full inbox, or maybe some temporary downtime of the website or their email server.

If you send attachments or larger emails, sometimes they will be rejected and handled as a soft bounce.

Soft bounces aren’t as much of a problem as a hard bounce but they’re usually added onto a deferral list, meaning they will continue trying for 24­-72 hours and then added to a suppression list.

It usually isn’t a problem, but if you have too many, it can be a problem if you don’t take control of the issue.

Long term, it can affect your sender reputation.

What is a Hard Bounce?

A hard bounce is more serious than a soft bounce and you will definitely want to take care of these.

The good thing is that hard bounces are usually removed by the email service you’re using. The bad thing is that if you have too many bounces on any particular send, you will end up getting banned or terminated from your account.

A hard bounce usually happens when the email address is no active or valid.

Maybe they deleted their email account, maybe when you scraped the email, the email was misspelled and not a real account, or maybe the domain expired, so the email goes nowhere.

To put it simply, a hard bounce is a permanent problem and a soft bounce is a short temporary problem.

A hard bounce instantly hurts your overall sender reputation with the receiving server.

So while the platform you use probably removes those hard bounces, if you have a lot of hard bounces, you’re in trouble, even if it’s only once.

Too many, you get banned, but even if you don’t get banned it can affect your future deliverability.

This is often the reason why a new domain will have great deliverability, but then after a few sends you’ll see a sharp decline in open rates.

So What’s The Solution To The Bounce Problem?

You have a couple options to go if you want to clean your email list from bounces.

You can use an email verification service. These services range in price and quality. I’m going to share with you how I clean my lists for a fraction of the cost that the verification services charge.

Actually, I’m going to show you 2 different ways you can do it.

Solution #1 – Using AmazonSES To Clean Emails

You’re will probably be asking why am use AmazonSES. Remember the goal here isn’t deliverability or getting into the inbox, the goal is to verify the validity of the email address.

The price is good as it cost about 10 cents per email.

You can spend a nice chunk of change verifying 100k emails, but using amazonSES you can spend 10 bucks for 100k emails to be sent, and get the bounces reported back to you.

I use some web based software called “Sendy” installed on one of my servers and have AmazonSES setup with the platform, so every time I get a hard bounce, the hard bounce is automatically removed from my list.

I can then export that list and import it into Mailchimp since I know the emails are good.

Setting up Sendy and configuring SES can be a bit difficult, so you’ll want to follow both the instructions for Sendy and SES to avoid any problems.

They have very detailed tutorials, that I couldn’t possibly expand on and make better. However, you don’t need to purchase Sendy, sendy is simply a web based platform to make things easier.

You can use any software to tie into AmazonSES and just manually remove the bounces.

SimplerSES is another service you can use, that uses AmazonSES and gives you a web based platform.

I haven’t used it other than a small trial but it’ll get the job done.

You can also use pretty much any other mailing software to tie into AmazonSES like Glock Easymailer which is also a good piece of software to send from your computer, it isn’t web based, but it can definitely get the job done.

They have a free trial so you can see if it’s right for you or not. Glock also has an email verifyer but I haven’t been able to attest to the quality of the product since I really enjoy my current setup and have no need for it.

There are other software clients as well that you can use to tie into AmazonSES. I can only recommend what I’ve personally used, perhaps there are better options out there, but I can’t in good conscience recommend something I’m not using or never have used.

Solution #2 ­ – Using Alternative Platforms to Clean Your List

MailChimp is really good at this, but there are other options you can use as an alternative or a backup.

Using alternative platforms to clean your list, eliminates the risk of you losing your main account with MailChimp.

Same concept with any platform you use. To save some money, use a basic account that allows you maybe 5,000 emails in your list, that way you can use that dummy account to do a first send, export the good emails, delete your list on that platform, then upload a new list.

Repeat until you verify all your emails.
