Scrapebox Email Verifier

[*Heracles*]

Hi Folks, just wanted to ask if anyone used the Scapebox email verifier? Do you find this tool effective at screening out spam traps and decreasing bounce rate etc?

I am a big fan of scrapebox, just haven't previously used the premium email tool : )

Cheers

It does reduce dead emails but it's still fairly high compared to using a paid service.

List with a premium email cleaner was 4% bounced emails.

Another list 9% bounced emails using ScrapeBox.

Another list with no cleaning was 17% bounced emails.

Those are actual percentages from different emails I've sent out using the same scraping method from the same site. The average bounce percentage moves around so cleaned is usually from 4-5% bounce rate and no cleaning 13%-17% bounce rate.

Thanks for sharing for experience. I have heard you must keep your bounce rate below 10% to stay away from blacklisting. Has that been your experience?

Even 1 mail sent to the wrong address can get you blacklisted, depending of the person who receives it. It's better to have targeted emails, or do some tests before you send them all.

spam traps are more dangerous than bounces because they are harder to avoid.

Geez, I wasn't aware 1 email could do that much damage. Are you talking about spam traps? what tests do you do before sending?

Any tricks for finding spam traps?

Are the spam trap lists you can check against?

 

[TomTheCat]

Yeah, I'm talking about spam traps. It's hard to find them unless you send them a test email with a link and see who opens it. A bot or a person. Also, I think is best to split the lists into 2. Free emails (Gmail, Yahoo!, etc.) and paid emails (the ones on bought domains). Also, search for disposable email addresses.

Thanks Tom, appreciate the guidance. Do spam traps normally include a bot which will open links? Do you typically find spam traps use paid domains or free?

 

[TomTheCat]

99% of the spam traps are automated. A bot will scan the email message and any link in it. If the link is suspicious, then is sent to security researchers that manually look into it. Most of the spam traps are on paid domains.

Verification is good so that your bounce will be in control but make sure your list is properly tuned with Spam traps, Invalid Syntax , Email domain validation ETC., They are so many third part services around who charge per mail and some provide with just package I would personally suggest Total bundle tools which comes in really handy you can try BulkEmailCleaner[dot]com

Good luck

staying below 10% is a must but I use Amazon SES and they contact you if you have more than 5%
before to use my email list, I remove all no valid emails.
then, to keep it below 5% without paying any bounce paid service, I delete all yahoo, Aol and few more free emails.
my last 21k email campaign got 2.63% bounces

I gonna take a look at BulkEmailCleaner[dot]com, but how they can check your list. I never used that kind of service before.

Verification is simple. You just need a server that will connect to the SMTP server of that email address, and ask their server if that user exists. Some domains have a catch-all email, so every username will return valid.

Here is the PHP code:

Will check it out for sure!! thank you

Found out many web services who offer bounce check and stuff like that but pretty expensive i'd say, surprised to see "free" code like you shared... appreciated

I also tested this: I have put many fake Gmail email addresses and my tool has not detected them.. all green and valid.. but in fact, its not.

 

[TomTheCat]

The code works. You just need to setup a valid email address so you can use the credentials. Google, will ban the IP address from where the script connects to their SMTP server if you check hundreds of emails in a short period. That's why you get those false positive results. That code works, but it needs tweeks in order to verify large lists of emails (rotating IPs/emails). Those services, as far as I can tell, will verify the email address only once. For example if 100 users submit the same email address to verify, they will process it only one time (during a specified period of time) to speed up processing times.

Hi Tom, been thinking about your comment on sending a test email to all emails with a link. The part I am a bit confused with is how you know if its a bot or person who clicks the link? Or do you hide the link so you know it could only be a spam trap bot who clicks it? Thanks again for your wisdom!

 

[TomTheCat]

It's very simple. You must have a log file that logs each visit. IP/Hostname/Country/Language/User-Agent/Email (add the email address encrypted in the URL you send, so you can detect the email address that is a spam trap). Then, you must check who owns the IP address. It's a tedious job, but if you build your own custom setup, you have high chances of hitting inbox in the future and avoid spam traps. Ideally is to filter the IPs, based on CIDRs. You build two lists of blacklisted IPs (datacenters, Tor, etc.) and whitelisted IPs (telecom companies, etc.).
