Is there a way to "warmup" an email that is configured and forwarded through Cloudflare's catch-all?

Services like instantly.ai expect your email to either be managed by Google et al or have POP3/IMAP credentials; is there a way to warmup an email that is managed through Cloudflare's catch all rules I am not thinking about? I am on the fre tier.
