A contact form on your website sends email, often from your own address, through the web server. If that server is not on your SPF record, the messages can be dropped or end up in spam.
Many forms send through the hosting server, with your domain in the From line. To receivers, that looks like email from your domain sent by an unknown server.
The hosting server is not on your SPF record and does not sign with DKIM. Strict receivers then treat the message as suspicious.
Send forms through your email provider's own sending service, using a proper login, so SPF and DKIM match. Or add the sending server to SPF.
Check the spam folder first. Some forms also report an error in a log that nobody reads, so a test message is worth sending.
