What is a Persona?
A "Persona" is a specific sender identity attached to an email address. For example, [email protected] is a persona. In the world of high-volume outbound, you cannot rely on a single persona to send 5,000 emails. You need a team of personas (digital twins) to distribute the load.
The "5 Accounts Per Domain" Rule
SendScale promotes a strict architectural best practice: Maximum 5 Email Accounts per Domain.
Why this suggestion exists: Deliverability reputation is shared at the domain level.
If you create 50 accounts on one domain ([email protected]... [email protected]) and one user gets flagged as spam, the entire domain is penalized. All 50 users go to spam.
By limiting it to 5, we force Horizontal Scaling. To send more emails, you buy a new domain. This compartmentalizes risk. If Domain A has issues, Domain B, C, and D continue running smoothly.
Adding & Removing Personas
Adding a New Persona
Navigate to Accounts.
Locate the "Add new" button.
Purchase your desired domain.
Enter the First Name, Last Name, and desired handle for each persona.
The monthly billing will update ($5/seat) automatically.
Managing Existing Personas
In the domain configuration view (as seen in the screenshot), you will see a list of all active personas on that domain.
Status: A green checkmark indicates the account is active and authenticated.
Deactivating: You can delete a persona by clicking the Red Trash Icon.
Warning: Deleting a persona permanently removes its warmup history and data. If you just want to stop spending money, consider pausing it, though billing is typically based on active seats.
Strategic Naming Conventions
When creating multiple personas for yourself, avoid using "Sales" or "Info". Use human names.
Variation Strategy: If your name is "John Doe", create variations to keep it unique across domains:
Why? This looks more natural to spam filters than having 50 identical john@ addresses sending identical content.
