A referral may not receive the email invitation sent through our referral form for a number of reasons. Your referral may have opted out of receiving marketing communication from Fidelity; the referral's SPAM filters may have prevented delivery; or the referral's email address may no longer be valid or may be blocked due to account compromise. If your referral indicates that he or she did not receive the invitation email, you can resubmit your invitation online or call a Fidelity representative at 800-652-7521 for help sending your invitations.
