Since Ryan acquired Smart Data Collective, we’ve paid close attention to how AI changes everyday marketing practices. You can now automate subject line testing, adjust content for different audiences, and personalize emails far beyond what was possible a few years ago.

It is becoming more common for teams to lean on AI to streamline email workflows. A SurveyMonkey study found that 51% of marketing professionals now use AI to create content for their email campaigns. Keep reading to learn more.

Email ROI Shows the Power of Personalization

There are few channels that consistently outperform email in terms of returns. OptinMonster reports that the average ROI for email marketing is 3,600%. You might be leaving money on the table by not tailoring your campaigns to fit each segment more closely.

You can save time and get better results by choosing platforms that include built-in AI features. It is helpful to use tools that test different designs, adjust send times based on user habits, and rewrite content to match tone. There are platforms that now give predictive suggestions based on past open rates and click-throughs. Your team can work faster without sacrificing personalization.

It is clear that AI is becoming a normal part of marketing work. Another study from SurveyMonkey found that 88% of marketers use AI tools in their daily tasks. You might already be doing the same without realizing it. It is smart to look for tools that match your workflow instead of forcing new habits.

There are many companies who are shifting their focus as AI takes over more routine tasks. The Digital Marketing Institute found that 75% of businesses using AI for marketing expect to focus more on strategy in the future. You can do the same by picking platforms that handle the busywork behind the scenes. It is no longer just about sending emails—it’s about building smarter campaigns.

To achieve successful email campaigns, it is best to avoid using new domains or accounts to send emails immediately. This is a common yet costly mistake that can cause email service providers (ESPs) to blacklist your accounts.

One way to get through is by conducting regular email warm-ups before sending emails out. Fortunately, platforms like Instantly provide consistent email warmups that foster a positive sender reputation and boost deliverability rates. 

This guide highlights our top five dedicated email warmup and deliverability platforms for successful email outreach in 2025. They include:
