After purchasing domains, the next step is to choose an ESP for creating email accounts.

We recommend using Gmail and Outlook for optimal deliverability.

Here are three important points to consider for this step:

  1. Create 5-10 domains per workspace/tenant.

  2. Limit to 3 mailboxes per domain.

  3. Send only 30-50 messages per day from each email address.

Below is a straightforward guide on obtaining the secondary domains and email addresses you will need for your campaign.

Tip—the number of emails you plan to send will influence your setup.

Popular ESPs vs SMTP Software

Email Service Providers (ESPs) are companies that offer email marketing and delivery services. They typically provide a platform for creating, sending, and tracking email campaigns.

Examples include Gmail, Outlook, Zoho Mail, Apple Mail etc.

ESPs often feature user-friendly interfaces that make it easy to design and send professional-looking emails without advanced technical skills.

SMTP Software, on the other hand, uses the Simple Mail Transfer Protocol for sending emails. It can be a standalone application or integrated into other systems.

Examples include Postfix, Exim, and Microsoft SMTP Server.

SMTP software provides more control over the email-sending process and is often used by organizations requiring a high level of customization for their email infrastructure.

Which Option is Better?

Deciding between an ESP and SMTP software depends on your unique needs and resources.

Opt for ESPs when:

  • You require a user-friendly platform to create and manage email campaigns.

  • Analytics, reporting, and ensuring high deliverability are important to you.

  • You prefer a managed solution that doesn’t demand extensive technical skills.

Opt for SMTP software when:

  • You need greater control over your email infrastructure.

  • You are sending a large volume of transactional emails from your applications or systems.

  • You possess the technical expertise to set up and maintain an email server.

Important Considerations

1. IP Tracing for Consistency

  • Consistently use the same IP address for sending emails from your workspaces or email accounts to establish a strong sender reputation and enhance deliverability.

  • Regularly monitor and maintain this IP address to ensure consistency.

2. Update Links and Notify Stakeholders

  • Utilize the same IP address for email sending from your workspaces or email accounts to maintain a good sender reputation and improve deliverability.

  • Keep this IP address regularly monitored and maintained for consistency.

3. Avoid Reusing Credit Cards (CC)

  • When setting up multiple workspaces or email accounts, use different payment methods or credit cards to prevent potential credit card-level blocks.

  • Frequent use of the same credit card might be perceived as suspicious behavior.
