I'm curious what strategies agents are using to write effective email subject lines in order to increase the readership of drip emails.

What strategies have you tried or tested? What has been the result?

I've spent a great deal of time coming up with & revising the subject matter & text in my drip email campaigns, but I've neglected this important area. It doesn't matter how good your email body is if people don't open the emails, right?

I think this task is easier for more generic emails such as newsletters, etc. where the benefit for the recipient of reading the email is easier to convey (they signed up for an email newsletter & here it is in their inbox).

I'm talking more about leads who have signed up to search homes on your website & the drip emails you sent to try to build trust, encourage interaction & ultimately lead to an appointment.
