9 Marketing Tips for Warming Up Your Email Address

Are you looking for ways to improve email deliverability and responses? Warming up your email address is a critical first step. This is where you gradually establish a positive reputation with email providers by sending relevant, engaging messages. 

When done correctly, this helps you comply with email providers’ algorithms and avoid sophisticated spam filters. Let’s discuss why warming up your email address works by reviewing 10 actionable tips that you can apply to yours.

1. Establish Trust With ISPs

When you send emails from a new or inactive email address, ISPs (internet service providers) are cautious about delivering your messages. By sending emails out in small batches over a period of several days, you gradually build trust with those ISPs. 

For example, you could start by sending emails to a small segment of engaged subscribers who are more likely to interact positively with your marketing.

2. Improve Deliverability

Deliverability refers to your emails’ ability to reach your subscribers’ inboxes. A warm email address is more likely to have better deliverability rates, which makes it more likely that your messages will be received, seen, and read.

Monitoring metrics of electronic engagement (open and click-through rates) using an email automation tool can help you gauge how effective your warm-up process may be. 

3. Enhance Sender Reputation

Your sender reputation plays a crucial role in determining whether your emails are delivered to inboxes or spam folders, or even get marked by blacklists. Warming up your email address helps improve your sender reputation over time, making it more likely that your future emails will be prioritized by ISPs. 

The best way to do this is by sending relevant and valuable content to your subscribers.

4. Build Customer Engagement

Engagement is key to a successful email marketing campaign. Warming up your email address allows you to gradually build audience interest by delivering content that consistently resonates with their needs. 

For example, segmenting your email list based on subscribers’ preferences and behavior can help you personalize their content far more than generic, high-level outreach.

5. Reduce Spam Complaints

Spam complaints can have a detrimental impact on your sender reputation and deliverability. By sending targeted, permission-based emails, you can minimize the risk of leads labeling you as spam — or worse, getting your domain blacklisted.

Providing clear opt-in opportunities and honoring unsubscribe requests promptly will help you maintain a positive digital presence (not to mention, it’s the law).

6. Maximize ROI

A well-executed email marketing strategy can deliver a high return on investment for your business. A warm email address ensures that your emails are reaching intended recipients and driving actionable results, like website visits or sales discussions. 

Track the performance of your email campaigns so that you can identify what topics matter most to your leads, then tailor your future messaging to reflect them. 

7. Establish Brand Authority

Consistently delivering high-quality content to your subscribers helps establish your brand as a trusted authority in your industry. Warming up your email address enables you to showcase your expertise and provide value to your audience, strengthening their loyalty.

That can include sharing informative articles, case studies, or how-to guides that position your brand as a go-to resource for information and insight.

8. Adapt to Changing Trends

It’s important to keep in mind that email marketing practices are always evolving. Once your email address is established, you can better adapt to changing trends and preferences among your audience, and ensure that your messaging remains effective. 

Monitoring industry trends and experimenting with new email formats, tools, and delivery times can help you stay ahead of the curve and maintain relevance with your subscribers.

9. Fostering Long-Term Relationships

Ultimately, the goal of email marketing is to build and nurture long-term relationships with customers. Warming up your email address sets the foundation for meaningful interactions and ongoing engagement, leading to increased customer retention. 

For example, sending personalized follow-up emails and nurturing campaigns can allow you to deepen connections with your new and established customers. This keeps your name on their radar, and offers greater opportunities to identify areas where you can assist them even further.

A Note About Cold Leads

Unlike an established database of leads who have opted in to receive your marketing, you may also try to add new contacts by using cold email outreach. This often involves purchasing contact lists or using automation that can find email addresses for the people you want to talk with. Because these leads have not opted in to receive your emails, it’s important that you:

  1. Send to small batches of contacts over the course of a day — 200 or less, preferably.
  2. Purchase a companion domain to send your emails from, rather than your core domain. This protects your core domain from becoming blacklisted. A companion domain will have a similar naming convention as your core domain, and will actually redirect to your core domain should anyone type it into a web browser, yet it will still be separate from that domain for the purposes of email automation.
  3. Use little to no images in the bodies of these emails, as inbox filters may interpret them as spam.


The best way to contact cold leads is to use prospecting automation (a service we offer), in conjunction with
these types of emails.
