Improve your email marketing...
Should you 'delete' or 'unsubscribe' your 'cold' email subscribers?
This is a question I often get asked when talking about email list hygiene - so, I'll share with you, what I think... (and do!).
Firstly, to avoid any ambiguity, what do I mean by 'cold' subscribers?
Well, essentially, the term describes subscribers on your email list who are not engaging in your emails - they're not clicking on links, not replying, they're not even opening them!
Email marketing platforms qualify 'cold' subscribers using varying models of measurement, however, if you use Kit then a 'cold' subscriber is someone who has not engaged for at least 90 days, or if they have been a subscriber for less than 90 days, then they haven't engaged for at least 30 days.
You can easily check how many 'cold' subscribers you have by applying the filter to your list;
In Kit, navigate to menu option: 'Grow' > 'Subscribers'
From the drop-down menu, select 'Cold Subscribers';
Okay, back to the initial question - delete or unsubscribe them?
Well, actually, the first thing I do is try to get them to re-engage - I'll send them a couple of emails with more impactful subject lines, like... "I think it's time to say goodbye..." - this (somewhat) sensationalised approach often gets them to at least open the email.
If they don't engage with the 're-engagement emails' - then it's time for them to disappear off your list! ('cold' subscribers can negatively impact your overall email deliverability rate).
Okay, so what do I do in my biz?... I unsubscribe them.
Let me explain why...
When a subscriber joins your email list, over time, they will get 'decorated' - what I mean by that is they will have certain tags applied to their profile; they'll be associated with an opt-in form or a series of email sequences, and they'll perhaps have gone through some automations.
Over time, their profile will become nuanced - meaning you'll have a better idea of their preferences, behaviours (i.e. what they open, what they click on, what interests they have etc.) - but most importantly, you'll have a record of all the emails they been sent.
If, on the other hand, you 'delete' them from your list - it means that if they ever re-join your list, you won't know what they've already received and you could send them emails they already have in their inbox.
The tldr; version...
I unsubscribe my 'cold' subscribers, and I do NOT delete them.
P.S. I run an automated list-cleaning process that checks every subscriber AT LEAST once every 90 days (some are checked more frequently) - and then, the automated process kicks in and a few days later, all 'cold' subscribers are either re-engaged or unsubscribed from my list. If you'd like a copy of my automation for your Kit account, let me know and I'll send you the link.
P.P.S. If any subscriber ever asks me to entirely delete their data, as is their right, then I obviously would respect their wishes and remove them entirely from my email list.
