If the link was sent by email, log into your email account through your email provider's web-based system (rather than using an email client, such as Outlook Express, or a phone app) and take a look to see if there's a 'spam', 'junk' or similar folder there. Quite a high percentage of genuine email gets trapped by spam filters. (Since they don't forward alleged spam to email clients or phone apps, you'll only see those missing emails if you go into the web-based service).
