The Mobile Personalization Companion

Personalization has officially taken center stage in the world of engagement, no longer as a luxury but as a necessity.

Hey {{first name}},

Let's get real — reading something that feels like it was made for anybody feels a bit hollow and disingenuous, right? Whether consciously or not, people will always seek out brands that make them feel instantly understood and valued. It’s up to you to make sure your messages stand out in the sea of sameness we’ve all come to know and put up with.

eCommerce & retail

Over half of push notification subscribers say that message irrelevance is the top reason they consider brand communications to be “spam.” Customer preferences evolve every month, and in eCommerce, your ability to keep communications relevant to those preferences is the difference between a sale and a stalled conversion.

The shortest distance between swipe and sale

Mobile messaging resonates most within the context of established purchase intent – in other words, your customers have already demonstrated their interest in specific products, services, or buying habits. By proactively collecting and then re-packaging your campaigns to reflect this unique data, you make every notification an intuitive and engaging touchpoint. You also reduce the effort required for customers to find products they are interested in, effectively streamlining the pathway from “passively interested” to “no-brainer purchase.”

77% of consumers have chosen, recommended, or paid more for a brand that provides a personalized experience.

Gaming

The top 25% of mobile games have an average monthly retention rate of less than 4%. Mobile gamers are notoriously hard to retain due to the vast number of available alternatives and the tendency for players to lose interest as soon as they’re not feeling challenged or rewarded.

Make every player feel like a champion

Personalized messaging empowers players by giving them a sense of ownership over their unique journeys within the game. By tailoring interactions to align with each player’s progress, preferences, and in-game achievements, you create motivating touchpoints that keep them deeply immersed in their mobile experience. This relevance ensures that every notification feels like a natural extension of their gameplay, meaning players are not just participants — they become the protagonists of their own journeys, driving long-term loyalty.

Fintech

The key to sustainable engagement in the fintech space is earning user trust. Message relevancy fosters this trust by consistently providing valuable and timely information that helps users manage their finances effectively.

Be more than a piggy bank

When users receive messages that are specifically tailored to their financial situation—such as alerts about low balances or personalized advice—they perceive your app as attentive and reliable. This attentiveness not only strengthens your users’ emotional connection to your app but also encourages consistent retention, the more secure your users feel.

Health & fitness

The average health and fitness app’s retention rate in 2022 was 37% on the first day, dropping to 9% by day 28.

As with a traditional gym routine, many users start their journeys with strong intentions but often struggle to sustain their engagement due to a lack of personalized support, relevant content, and timely encouragement.

Providing value beyond the app

With success in this vertical so dependent on user goal-setting and personal motivation, it makes sense that personalization plays such a crucial role in slowing churn and retaining users over time.

When users receive tailored reminders, progress updates, and motivational prompts that align with their specific goals and behaviors, it reinforces their commitment to their health and keeps them engaged. By celebrating small victories, personalization helps maintain the momentum needed to achieve long-term fitness goals, making the experience not just about completing tasks but about continuous personal growth and success.

Yuliia Hryshchenko
“We use personalization in two ways: first, to segment users, and second, to personalize the information in a message. When a user sees their target weight or their age in a message, it makes it more about them — and it’s more likely to work.”

Media

Media apps face a unique uphill battle in maintaining user attention in a highly competitive and content-saturated environment. There’s always another option and users can easily become overwhelmed or distracted, leading to lower engagement rates and app abandonment.

Empowering user content consumption

Personalization satisfies users’ desire for relevance, making their experience more meaningful and engaging. It also addresses the implicit need for convenience, helping them quickly find what they want in a sea of content, which reduces decision fatigue. As a bonus, this experience enhances the feeling of autonomy, empowering users to feel in control of their media consumption.

These psychological factors directly encourage metrics like increased session duration, higher content consumption rates, and improved user retention.

Media personalization essentials
