This guide explains how to set up a reliable email deliverability system when using FirstQuadrant for outbound email campaigns. It outlines the risks of poor deliverability, how to use separate domains and mailboxes, and how to calculate the number of mailboxes required. You’ll also find best practices for warming up email addresses and maintaining your sender reputation, including recommended services and configuration steps within FirstQuadrant.
When using FirstQuadrant to send outbound email campaigns, it is crucial to establish a solid email deliverability setup. This ensures that your emails do not get blocked and reach your recipients’ inboxes.
If you send mass emails from your primary email address without proper setup, you risk triggering spam filters. This can lead to your email address—and eventually your entire domain—being marked as spam. Once this happens, none of your emails, including non-outbound ones, will land in inboxes.
To prevent this, a well-structured email deliverability setup is essential. This involves using separate domains and email addresses for outbound emails.
FirstQuadrant allows you to add unlimited email addresses per team member, making it easy to scale your outreach while maintaining high deliverability.
A strong deliverability setup consists of:
You can either:
These domains should resemble your primary domain. Example:
example.com
, new domains should be similar, such as tryexample.com
Each mailbox should have different permutations of your name:
[email protected]
, [email protected]
, [email protected]
A fully warmed-up mailbox should send no more than 20-25 emails per day (conservative estimate). This is also the default setting in FirstQuadrant. To change the daily sending max:
Formula: Total emails per month ÷ 25 work days ÷ 20 emails per day = Required mailboxes
Additional considerations:
**Info: **To calculate the real costs of your outbound campaigns read our article on the true cost of outbound emails at scale
5,000 ÷ 25 days ÷ 20 emails per day = 10 mailboxes
13 mailboxes ÷ 4 mailboxes per domain = 3 new domains
Once you’ve set up the different mailboxes you need to connect and add them to FirstQuadrant.
Once mailboxes are set up, warming them up with a dedicated warming service is essential. This process makes your email accounts appear active and legitimate, reducing spam filter risks.
We advise using dedicated email warming services, rather than platforms that bundle warming with other features, as dedicated services provide better infrastructure and results. A good warming service we’ve used in the past is mailreach.co
By following these steps, you will ensure optimal email deliverability, maximizing your outbound email success while safeguarding your domain reputation.
