2 – Sending from a free domain email address

Using a ‘from’ address that is a domain other than your own is a definate no! This will instantly perceive you as spam and damages your deliverability.


3 – Subject lines

Check your subject lines! Does it come across as SPAM?

Also ensure that you limit the use of characters such as £ or ! as this will often send emails straight to the spam folder.


4 – Use of images

Consider your choice of images for 2 reasons:

A – Using overly large images without any supporting text in your email can be a flag for SPAM filters (historically this is one way that SPAM mail could get through). There is currently no definite guidelines on text/image ratio, but general advise would be 60/40 text to image. However test and track and please do share your results!

B– Make sure that you consider the use of images and equally how does this view on mobile? Always ensure that you also have a text version for those who don’t accept HTML.

arpReach handles this with ease with a simple tick box ‘multipart’ which delivers both an HTML and text version of your email.


5 – Sending to unengaged recipients

Low open rates are a signal to ISPs that your recipients are not engaged with you, and your content is not relevant to them. This lack of engagement is just one of the factors that ISPs will use as part of your sender score and so could effect delivery of future emails. Worst case scenario they could even block your campaigns!

Therefore ensure you are monitoring your email campaigns and segmenting and targeting to get the best possible engagement.

  1. What do you do if subscribers miss your first email entirely? Maybe their inbox was full that day, or you just sent it at a bad time. When this happens, you can always resend the email a few days later to re-engage the “non-responders. ”
