Never recieving verification in Gmail

Greetings, I am encountering an issue with Gmail specifically regarding verification emails. Despite testing with six different Gmail accounts, I have not received any verification emails, not even in the spam folder. I have tried other email services like Yahoo and ProtonMail, and they function properly, although most of the emails end up in the junk or spam folders. My website is legitimate, and I am unsure if this could be a factor. Additionally, I utilize Cloudflare, which may be relevant to the situation.

I would appreciate any assistance as my website’s theme is integrated with this plugin, which I find excellent aside from the aforementioned Gmail verification email issue.
