How to Set Up Provider Preferences for Your Email Warm-Up

Take control of your email warm-up strategy with customizable balancing options

Why Mailbox Balancing Matters

By default, Warmy’s AI sends warm-up emails to all major email providers (e.g., Gmail, Outlook, Yahoo). While this ensures broad coverage, it’s not ideal for targeted campaigns. Mailbox balancing lets you:

  • Focus your efforts on providers your audience actually uses.

  • Avoid wasting resources on irrelevant providers.

  • Improve deliverability by building a reputation with the right email systems.

Example:

  • B2B campaigns need a reputation with business-grade providers like G Suite or Microsoft 365.

  • B2C campaigns should prioritize personal email providers like Gmail, Outlook, or Yahoo.


How to Configure Mailbox Balancing

Step 1: Access the Balancing Settings

  1. Log in to your Warmy dashboard.

  2. Go to Profile> Warm-up Preferances

    • Tip: You can also access this from your mailbox dashboard. 


Step 2: Choose Your Audience Type (B2B or B2C)

This is critical for success!

  • For B2B Audiences (Businesses):
    Focus on business email providers:
    ✅ G Suite (Google Workspace)
    ✅ Microsoft 365 (Outlook for Business)
    ✅ ZohoPro
    ✅ Custom SMTP/self-hosted servers
    Avoid: Personal providers like Gmail, Yahoo, or Outlook.com.

  • For B2C Audiences (Consumers):
    Focus on personal email providers:
    ✅ Gmail (personal)
    ✅ Outlook (personal)
    ✅ Yahoo
    ✅ AOL
    Avoid: Business-specific platforms like G Suite or Microsoft 365.

⚠️ Warning:

  • Not sure? Contact Support immediately. Misconfiguration can ruin your warm-up progress.


Step 3: Set Provider-Specific Percentages

  1. Under Provider Distribution, allocate percentages only to relevant providers (see Step 2).

    • Example for B2B: 50% G Suite, 30% Microsoft 365, 20% ZohoPro.

  2. Ensure the total equals 100% (the system will validate this).

  3. Click Save to apply.


Step 4: Enable/Disable Manual Balancing

  1. Toggle Manual Balancing on/off.

    • On: Use your custom provider percentages.

    • Off: Warmy’s AI sends emails to all providers (not recommended for targeted campaigns).


User-Level vs. Sender-Level Settings

You can configure balancing preferences at two levels:

User-Level Sender-Level
Applies to all mailboxes by default. Overrides user-level settings for specific senders.
Ideal for teams with consistent warm-up needs. Use this to customize individual campaigns or exceptions.

⚠️ 
Sender-level settings always take priority over user-level configurations. Configure individual senders carefully to avoid conflicts.

Example:

  • User-Level: Set B2B preferences for all mailboxes.

  • Sender-Level: Adjust one mailbox to B2C for a specific campaign.

    • Result: The B2C mailbox ignores user-level settings and uses its own configuration. All other mailboxes follow user-level rules.

Key Notes to Avoid Mistakes

  1. Default Behavior: If you don’t configure balancing, emails go to all providers—ideal for general use.

  2. New Mailboxes: Settings apply automatically to new mailboxes unless overridden at the sender level.

  3. Priority Rules: Sender-level settings override global preferences.


What Happens If You Choose the Wrong Providers?

  • B2B Example: Warming up with Gmail (personal) instead of G Suite means your emails won’t build reputation with corporate email filters.

  • Result: Poor deliverability to your actual audience.

  • Fix: Double-check settings or contact support for a configuration review.
