I'm not aware of any reason why that would be the case, but if you have any information from email headers or server logs I'd be grateful to see it.Any "small" mass mailing is likely to be identified as spam
In the emails I've seen, the specific reason they went to spam was failing the DMARC check because the domain in the nominal 'from' address (membership@british-caving.org.uk) didn't match the Return Path domain or the DKIM-Signature domain which was sendgrid.net
