on click .. Suspicious link error in gmail(laravel)

Question

When a user signs up on our website, they get an email verification link, but whenever they try to click on any link in that mail, they get the alert error message:

Suspicious link

This link leads to an untrusted site. Are you sure you want to proceed?

We are using the sendgrid mailer system and we are certified to https.

Where is the problem coming from?

Answer 1

This is mostly in newsletters(Mailers), we need to verify the domain in Google

For authenticating domain using the steps below:

1. Go to postmaster.google.com.

2. On the bottom-right, click the + button.

3. In the box that pops up, enter your authentication domain.

4. Next, prove that you own the domain by adding a DNS TXT or a DNS CNAME record.
