How AI Warmup Improves Email Deliverability | Smartlead

Smartlead analytics show that businesses can experience up to a 50% increase in open rates and a 30% boost in click-through rates by employing a strategic warmup process. 

However, building high email deliverability while managing crucial aspects like sender reputation, email list quality, and content can seem like an overwhelming task. 

What is Email Warmup?

Email warmup is the strategic process of gradually establishing a positive sender reputation for a new email account or sender domain. It ensures that your IP or emails are not perceived as spam by the internet service providers (ISPs).

Essentially, email warmup is the calculated measure taken to build and maintain email deliverability. This process ensures a new domain or email account reaches its optimum sending potential, ensuring your messages resonate positively with both automated filters and human recipients.

Email warmup is done by sending a relatively lower number of emails and gradually increasing the number of emails sent (ramp-up) over a predetermined period. This practice aims to signal to ISPs that your email-sending activity is legitimate, fostering trust and improving the likelihood of your messages reaching recipients' inboxes instead of being flagged as spam.

When you create a new email account or migrate from one ESP to another, you get a predetermined daily sending limit for the email account. For example, Gmail Workspace accounts come with a daily sending limit of 2000 emails. However, you can’t start using the full potential right away, and you have to start with a much lower sending volume. 

At Smartlead.ai, we recommend at least two weeks of email warmup for optimum deliverability. If you have the luxury of warming up for one month, definitely do it - else, two weeks is fine. 

How does AI Warmup Improve Email Deliverability?

AI warmup involves gradually increasing the volume and frequency of email sending from a new or less active email sender domain to establish a positive reputation with email service providers (ESPs) and improve email deliverability. Here's how AI warmup can improve email deliverability:

1. Builds Sender Reputation

Email service providers evaluate the reputation of email senders to determine the fate of their emails – whether they land in the inbox, spam folder, or are blocked altogether. AI warmup enables senders to incrementally increase their email volume, showcasing legitimacy and non-spammy behavior to ESPs.

2. Avoids Spam Filters

A sudden surge in email volume from a new or inactive sender can trigger spam filters. AI warmup neutralizes the risk by starting with a small volume of emails and gradually increasing it (ramp-up), mimicking human-like email-sending behavior.

3. Predictive Analytics

AI warmup tools such as Smartlead can analyze historical email performance data, identify patterns, and predict the optimal email sending patterns and volume for a successful warmup. AI can help determine the right balance between the number of emails sent and the risk of hitting spam traps or receiving high bounce rates.

3. Establishes Trust

Over time, AI warmup allows email senders to build trust with ESPs. Consistent positive behavior in sending emails fosters trust, making ESPs more inclined to believe that the emails are not malicious or unwanted.

4. Reduces Bounce Rates

Sending a large number of emails without a proper warmup process can result in high bounce rates, indicating that a significant portion of the emails couldn't be delivered. AI warmup helps identify and address deliverability issues early on, reducing bounce rates.

5. Improves Open Rates

A positive sender reputation achieved through warmup enhances the likelihood of emails being delivered to the inbox. Higher inbox placement contributes to improved open rates, as recipients are more likely to see and engage with emails that don't end up in spam folders.

6. Engagement Analysis and Spam Detection

AI can monitor email engagement metrics such as open rates, click-through rates, and conversion rates in real time. It can identify which emails are resonating with recipients and which ones are not, allowing you to adjust your email content and strategy accordingly.

Warmup can help identify potentially spammy content within your emails, reducing the likelihood of your messages being flagged as spam. By avoiding spammy keywords and phrases, you can improve email deliverability.

Besides these, AI warmup can also help in: 

  • Send Time Optimization: AI can analyze recipient behavior to determine the optimal times to send emails to different segments of your audience. Sending emails at the right time can lead to higher engagement and improved deliverability.
  • Feedback Loop Analysis: AI can assist in monitoring feedback loops, which are mechanisms that allow ESPs to report complaints and issues directly to senders. Analyzing this feedback promptly and taking necessary actions can prevent deliverability problems.
  • Adaptive Warmup: AI can dynamically adjust the warmup process based on real-time feedback and changes in recipient behavior. If engagement decreases or spam reports increase, AI can recommend slowing down or making necessary adjustments to avoid harming your sender's reputation.

AI Email Warmup to Scale Sales Outreach

Email warmup may seem time-consuming, but it drastically reduces the time to build your sender reputation. If you directly start sending emails without warming up your inbox, it may take months to make a positive sender reputation. 

On the other hand, warming up your email account will take around two to three weeks (while gradually increasing the number of cold emails sent), and you have a good sender reputation to run your email campaigns. 

Bulk sales emails can trigger spam triggers for ESPs. Sending shortened URLs and images also triggers spam filters, as most spammers use this method to send phishing emails. Of course, you can bypass spam traps by sending plain text emails and full links to domains with high DA (Domain Authority). Email warmups can automate the process of sending, opening, and replying to your emails to build trust among ESPs and improve deliverability for your inbox.

FAQs

How do you warm up an email?

To warm up an email address or sender domain effectively, follow these steps:

  • Begin by sending a very small volume of emails, well below your eventual sending limits. For instance, if you have a new email account, start with just a few emails per day. Over a period of two to four weeks, slowly increase the number of emails you send each day. This gradual ramp-up signals to email service providers (ESPs) that your email-sending activity is legitimate and not spammy. A typical warmup schedule might start with 4-8 emails per day and gradually increase to 20-30 emails per day after two weeks. Ensure that you maintain a positive sender reputation by monitoring your email engagement and adjusting your strategy as needed. Remember to configure essential email authentication protocols like DKIM, DMARC, SPF, and MX records to boost your credibility and improve deliverability.
