Custom Domains

TalkBox offers a “custom domain” feature to customise the Sender. This allows users to change the address of the Sender, so that it is the same as the From address.

For example, if you create an email sender in TalkBox, with the name “Your company” and address “hello@news.yourcompany.com.au”.

This will come through as the From address, and has a different domain from the default TalkBox sender: talkbox.email.

This is displayed differently across email clients: take Gmail which emphasises From and Outlook that emphasises Sender.

Gmail

From: Your Company <hello@news.yourcompany.com.au> via talkbox.email

Outlook

Sender: hello=news.yourcompany.com.au@talkbox.email on behalf of Your Company <hello@news.yourcompany.com.au>

Not all versions of Outlook display the “Sender”, newer versions display the “From” instead

A custom domain will mean that the From and Sender addresses will align (the same domain), and effectively remove the “via talkbox.email”.

While this will also allow the From address and Sender address to be aligned per a strict DMARC policy, this is primarily a cosmetic feature and is not required to ensure deliverability.

With a custom domain, the email client will instead display the following

Gmail
From: Your Company hello@news.yourcompany.com.au

Outlook
Sender: hello@news.yourcompany.com.au

Warming Up

Once your custom domain has been verified by our team, you will need to ‘warm up’ your domain.

This is to stop your domain reputation being downgraded and your emails being flagged as spam. Generally, this means that you forego sending huge amounts of emails initially and step up your sends over time to your expected daily level.

We suggest the following timeline to follow:

Each stage is equal to one day, you can follow the daily or the hourly limit per day.

We recommend targeting your most engaged recipients during the warm-up process to ensure that you see good open and click rates. Sending to engaged recipients gives a huge boost to reputation because of initial positive reactions to your messages.

For some mailbox providers like Gmail, it is especially important. Gmail uses engagement as one of its main metrics to determine mailbox placement.
