Yes. But not while they were here as Airbnb guests. At that time, it didn’t occur to me that we’d be more interested in direct booking in the future.
I have stayed in contact with past guests. We’ve sent them our annual holiday letter, and I’ve had lots of text exchanges with many of them, asking about their family, travels, etc. For just about every guest, I’ve kept some notes about things we talked about during their visit here, so I can easily text to follow up about those topics.
Since the pandemic began, I’ve twice texted all past guests we’d be interested in hosting again, talked about vaccination status, and invited them to contact me by text or phone if they want to stay with us again. I did that last summer, when we were briefly open to “repeat offenders,” as my husband calls them. Then I texted again earlier this year.
We don’t have a separate booking website, either. We do have a simple one-page website where people can easily find our contact info.
As for ethics, Airbnb “introduced” us to these guests, and they all completed at least one Airbnb transaction with us. Now we know each other. We don’t need Airbnb to “introduce” us again.
