Gmail Security Update: How Trustpilot Ensures 30% of Your Emails Aren't Classed as Spam

Google have announced changes to Gmail in order to tighten email security. But what does it mean for you?

Well, on emails in Google, you might notice a small red padlock on some emails.

That small red unlocked padlock indicates that the message is potentially unsafe. This doesn’t mean that it’s necessarily going to infect your computer or anything, but it does mean the email hasn’t passed Gmail’s new encryption and authenticity rules.

However, with Trustpilot’s review invitations, this icon will not appear.

And that means maximum security and privacy when you communicate with your customers.

Here is what's new

In summary, Gmail just got a whole lot safer thanks to additional encryption and authentication systems.

Trustpilot’s review invitations already comply with Gmail’s security measures. If you’re a Trustpilot customer, sending review invitations through Trustpilot ensures email recipients always receive their review invitations and don’t end up in spam.

And that’s important - almost 30% of review invitations are sent to Gmail accounts.

So while businesses are welcome to use their own email systems, Trustpilot’s system works hand-in-hand with Gmail. More than 60% of our customers already use Trustpilot to send out invites.

With continually optimised review templates, engagement with our review invitations is already high as it is.

Couple a good standard invite with assured security, and that means it’s easier, quicker, and safer for you to send out our review invitations than ever before.

Explained: Encryption & authentication changes

There are a few things to note here, all summarised with acronyms, that apply to encryption and authentication.

On the face of it, they seem a little daunting. But let’s take a look at what they mean, and why Google’s measures really add a welcome layer of security.


  • Transport Layer Security (TLS): A layer of security maintaining privacy between applications and internet users. So when you send an email, TLS ensures that no one else reads your conversation. Think of it as a ‘digital handshake’ between what you send and the receiving person.1


  • Domain Keys Identified Mail (DKIM): A coding measure ensuring the text and content of an email wasn’t changed between the sender and the receiver by associating a domain name with the email message. It’s a bit like a ‘digital signature’ vouching for authenticity.2 so people cannot impersonate a particular web domain and send messages on their behalf, which is a common phishing technique.
  • DMARC: A standard stopping spammers from using domain names that they have nothing to do with (also known as ‘spoofing’). So even if the previous measures fail, an email from a ‘spoofer’ will not even reach the intended recipient.3

The result?

Safer, more secure, simpler email communication. And Trustpilot is already part of it.
