In general, try to send emails on Tuesday, Wednesday or Thursday mornings or afternoons for the highest open rate. And A/B test if possible.
According to HubSpot, the best time to send an email is on Tuesdays at 11am EST. So, if you send an email as this time will it be opened? Maybe.
The best time to send a email depends on your target audience. Think about when your prospect is most likely to be checking their email (morning, afternoon, or evening) and do some A/B testing.
