Warm Up Your Gmail Account

In the digital age, where email communication dominates both personal and professional spheres, the art of sending effective cold emails remains crucial. Whether it’s for business development, networking, or marketing purposes, ensuring your emails reach the recipient’s inbox is paramount. This guide is tailored for individuals or businesses using Gmail and planning to leverage the Mailway Mail Merge addon for their cold email campaigns.

A cold email is an unsolicited email sent to a potential contact with whom you have no prior relationship. It’s a powerful tool not just for marketers but also for professionals extending invitations, sharing newsletters, or making introductions.

In response to the growing threat of spam and phishing, Google updated its Spam and abuse policy in 2019, introducing more rigorous email filtering mechanisms. These changes, while challenging, have not made it impossible for digital marketers to reach their audience effectively.

Warming up your Gmail account is a strategic process aimed at building a solid reputation and ensuring high deliverability rates for your emails. This preparation is essential for anyone looking to embark on mass email campaigns.

Below, we’ve expanded our list of best practices for warming up your Gmail account and ensuring your emails land in the inbox, not the spam folder.

1. Personalize Your Account

  • Add a Profile Picture and Email Signature: A professional profile picture and a personalized email signature at the end of your emails signal to Google that you’re a genuine user, not a bot.

2. Gradual Email Volume Increase

  • Start Small and Scale: Begin by sending 10-12 emails on the first day, gradually increasing your volume by approximately 20 emails daily. This method helps Google recognize your account’s natural growth. Ensure diversity in your recipient’s email domains and meticulously validate their addresses to minimize bounces.

3. Humanize Your Communications

  • Craft Personalized Emails: Use a clear subject line, proper greetings, and include attachments or images that you’ve created. Aim for interactions and replies to demonstrate active engagement. Avoid using a no-reply sender address during this phase.

4. Regularly Clean Your Email List

  • Maintain a Healthy Contact List: Regular verification of your email list is crucial. Remove inactive or invalid addresses promptly. If recipients report your emails as spam, engage with them to correct this perception.

5. Timing Between Emails

  • Space Out Your Emails: Maintain a minimum 30-second interval between sending emails during the warm-up phase to mimic human behavior.

Additional Tips for a Successful Warm-Up Process

  • Engage With Recipients: Encourage replies and interactions to show Google your emails are welcomed and valued by recipients.
  • Monitor Unsubscribe Rates: A low unsubscribe rate is indicative of relevant and engaging content. Aim to keep this number minimal.
  • Use Email Warm-Up Services: Consider leveraging automated services designed to warm up email accounts by gradually increasing sending volumes and ensuring interactions.
  • Feedback Loops: Pay attention to feedback from your recipients. If they mention receiving your emails in their spam folder, take immediate action to address and rectify this.


  • How long does the warm-up process take? Following these best practices, your Gmail account should be adequately warmed up within 3-4 weeks. However, for optimal results, continue the process for up to 4-6 weeks.

  • What’s next after warming up? Once your Gmail account is fully warmed up, you’re ready to utilize the Mailway Mail Merge addon for your cold email campaigns, ensuring higher deliverability and engagement rates.

By adhering to these updated guidelines and tips, you’re setting the stage for successful email campaigns that reach their intended recipients, fostering meaningful connections and driving your business or personal goals forward.
