Use A/B Testing if you want to compare results for alternative subject lines or 'from address'. This is recommended to work out what generates the best email deliverability and open rate results.
One of the unique benefits of A/B testing is the ability to minimise risk with headlines that may send your emails to spam filters, such as using CAPS or words like; "sale", "free", "rich" or "deal" these have a higher likelihood of being flagged by spam filters.
Our data shows there can be differences of 10-20% in open rates based ONLY on changes to subject line. A/B Testing is very quick to set-up and it's worth a few minutes of your time to learn how!
