πŸ‘‹ Product Hunters, Almost all of us are familiar with the challenges of keeping our email lists clean. Keeping your lists clean not only helps maintain your sender reputation but also decreases unnecessary costs and frustrations. However, though not complex, it is extremely tedious and time consuming to keep an email list clean. Especially if you have a growing subscriber base and the tools you use do not have required checks in place. We were also in such a situation with our mailing lists and that is when we built a list cleaner that is useful yet simple while respecting privacy by design. Our list cleaner works right in your browser, ensuring that your subscriber data does not leave your computer. You can also save your original list with detailed diagnostic style comments. πŸ™† What it does? 1. Weeds out duplicates 2. Removes all emails with invalid TLDs (There are 1543 Known TLDs) 3. Detects high risk domains (We currently track 3753 High Risk Domains) 4. Filters emails with bad syntax. πŸ™… What it does not do? 1. Deliverability Check 2. Detect Catch all 3. Detect spam traps/honey pots etc. πŸ’ What more should you know? 1. It is a free tool. 2. The tool comes with complete data security 3. The tool is GDPR/Privacy laws compliant by design Please let us know your thoughts/feedback πŸ™. We'll also be more than happy to open source this if enough of you want it. Just let us know. Thanks @abadesi for the hunt. Much appreciated πŸ™
Just cleaned a sample list...looking good...Will probably be using it a lot from now on. Hope you guys don't take it offline πŸ˜„
I can't believe how this product is free given how useful it is. It works a charm, and running in the browser is amazing in the privacy age. @p12dpraneeth how does this compare to other similar services?
@philip_kallberg The scope of the tool is to clean the email lists right in your browser without infringing your data privacy. In comparison to other similar services, the USP for MailSwift's Email List Cleaner is that it is free, it doesn't require data to be uploaded and hence, it is GDPR / privacy laws compliant by design.
@p12dpraneeth that's great, thanks for explaining. will be using this going forward.
I uploaded a list with 3 people only (to test), but it's stuck and won't do anything. Is it working?
I just checked it and it is working fine @thiagoafram There are two steps in the email list cleaning process. Step - 1: Browse your email list file (should be a CSV), select the column name of the email and then click continue Step - 2: If you have an unsubscribe email list, then browse that file (should be a CSV again), select the column name and click select. In case if you don't have an unsubscribe list, click on SKIP to skip this step Once you click on skip or select (based on unsubscribe list availability), the list cleaner will clean the list and provide you with multiple download options. Please check it once again. Let me know if you are still facing issues
@p12dpraneeth Just tested again, not working. 1. Downloaded my MailChimp list (CSV) 2. Uploaded / selected the column / skipped unsubscribe 3. Nothing happens
@thiagoafram I just checked with a bigger email list and it worked fine. Can you please help us with the following information to trace the bug 1. On which browser have you tried Email List Cleaner 2. What is the size of the list ? If the list is really huge (email list above 100K contacts), it might take a few seconds to clean the list and present the results
@p12dpraneeth 1. Chrome on Windows (Version 67.0.3396.87 (Official Build) (64-bit) 2. Only 3 people, as I mentioned on my first comment. It doesn't do anything. It's stuck on zero. Also, the button at the bottom for lifetime deal doesn't work either. I just tried on my mac/safari: same thing
Hey @thiagoafram! I will connect with you offline to get to the bottom of this πŸ€”. Seems to be working fine for others.

I've been using this to clean my email lists for a while, and it works great. It has reduced my bounces significantly and I love that it runs in the browser. In the privacy age it's great to know that I can control my own data locally.


Very easy, great results, runs 100% in browser


Not entirely sure how it scales - haven't tried any lists with 10k+ records
