1. Perfect Your Timing
While you won't be in a position to pinpoint the ideal time, it is worth running some A/B tests so that you can identify which timeframes work best for your campaign and then explore these options in future campaigns.
Timing can make a massive difference in whether your subscribers open your email and how successful you convert. So think carefully about what time and what day you send your emails.
2. Create Amazing Content every time
You might think that if a subscriber opens an email from you, they are essentially winning the battle. The content of your email influences your open rate.
This is why: If your subscribers are satisfied with your content, they will be more likely to open future emails. You may find that they look forward to your emails. If subscribers are unhappy with the content of your email, they won't open it again and may even unsubscribe.
You could send out a monthly or weekly newsletter that is packed full of tips and tricks but make sure it is relevant to each segment of subscribers.
