Introduction:

Master Domain

In cold email outreach, the success of your campaigns greatly depends on your email deliverability. Warming up your domain and email accounts properly ensures that your emails land in the inbox rather than the spam folder. In this article, we’ll cover the best practices for warming up your domains and email accounts, along with a step-by-step warmup plan for optimal results.

Why Warm Up Your Domain and Email Accounts?

  • Improve Deliverability: A warm email account is more likely to reach the inbox rather than the spam folder.
  • Build Trust with ISPs: Internet Service Providers (ISPs) look for signs of legitimate email sending. A properly warmed-up domain and email account can avoid being flagged as suspicious.
  • Maximize Open Rates: Warmup increases the chances of your emails being opened, improving campaign performance.

Email Warm-Up Strategy for SalesTarget.ai Users

In order to maintain the reputation of both your domain and email accounts, following a proper warm-up strategy is essential. SalesTarget.ai users should adhere to the following email sending limits:

Domain Limit:

  • Each domain can support up to 5 email accounts
  • All accounts within the same domain share the reputation, so warm-up should be handled carefully across all accounts.

Email Account Limit:

  • Each email account can send up to 30 emails per day to avoid being flagged as spam and to maintain a positive sender reputation
  • This volume ensures that the account doesn't trigger spam filters or raise concerns with ISPs (Internet Service Providers).

Warm-Up Plan for SalesTarget.ai Users

1. Initial Phase (Days 1–7):

  • Daily Emails per Account: Start with 5–10 emails per account per day.
  • Focus: Send emails only to trusted contacts (e.g., internal colleagues or known contacts) to start building engagement.

2. Progression Phase (Days 8–14):

  • Daily Emails per Account: Gradually increase to 20–25 emails per account per day.
  • Focus: Include real prospects and encourage engagement (opens, replies). Use personalized subject lines and content.

3. Full Capacity Phase (Days 15 and beyond):

  • Daily Emails per Account: Once the domain and email accounts have gained a good reputation, the daily limit can be gradually increased to 30 emails per account.
  • Focus: Ensure that emails are highly relevant and that there is continued engagement to keep the reputation strong.
Case Study

Tips for Successful Warm-Up:

  • Monitor Email Activity: Regularly check open rates, replies, and bounces. High bounce rates or low engagement may signal issues with warm-up.
  • Avoid Spammy Content: Stay away from all-caps, excessive links, or too many attachments in your emails.
  • Build Trust: Focus on sending emails that encourage interactions, whether that’s replying or clicking links, to improve your engagement signals.
  • Use the Right Tools: Leverage domain and email reputation monitoring tools to track your progress and adjust the warm-up strategy accordingly.

By following these limits and strategies, you'll ensure that both your domain and email accounts maintain their reputation, increasing the likelihood of your cold emails being delivered to the inbox.
