The subject line should link seamlessly to your main headline and then to the lead copy and into the body of the email.

What does your current email marketing performance look like? Analyse the performance of key metrics such as Open Rate, Click-through-Rate (CTR), Deliverability Rate, Unsubscribe Rate, ROI. What is working well and what isn’t. This can also be internally focused – for example, maybe it is taking a long time to create email content, or the creation process is inefficient.
