Q:

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

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?

A:

This is mostly in newsletters(Mailers), we need to verify the domain in Google 
For authenticating domain using the steps below:

Go to postmaster.google.com.
On the bottom-right, click the + button.
In the box that pops up, enter your authentication domain.
Next, prove that you own the domain by adding a DNS TXT or a DNS CNAME record.

Also it happens when we have https(ssl) but we are using the link http

A:

We were recently having this issue in our account verification emails as well. Verifying our domain through DNS records as recommended by Google was not enough. 
The ultimate solution for us was ensuring that every link has an alt tag with descriptive text.
<a href="https://example.com/verify" alt="Click here to verify your account">Verify!</a>
