Factors to Consider When Choosing an Email Marketing Platform

Before choosing an email marketing platform, consider how you’d use it. While all of the tools mentioned are good options to consider, they may not all be the right fit for your needs or goals. To choose the right tool for your business needs, consider the problem you want to solve rather than the tool's popularity. 

Narrow your options by asking yourself the following questions: 

Do I need a simple way to send newsletters?

If you’re just getting started, a smaller business, or managing straightforward campaigns, you might be best to begin with user-friendly platforms like Mailchimp or Brevo.

Do I need help identifying who to reach before I send an email?

If you’re focused on prioritizing high-intent leads and timing your outreach, Osserva offers advantages beyond standard email marketing by surfacing intent signals and triggering action based on real buying behavior.

Do I want built-in landing pages, funnels, or webinars alongside email? 

A platform like GetResponse can help if your strategy includes lead magnets and conversion paths.

Is my primary goal driving e-commerce revenue through email and SMS? 

Tools like Klaviyo and Omnisend are designed to help you understand purchase behavior, make product recommendations, and track revenue.

Do I need advanced automations across the customer lifecycle? 

ActiveCampaign or HubSpot offer strong automation tools and control, especially if you’re building complex customer journeys tied to engagement, site activity, or CRM data.

The best email marketing platform is the one that best supports your business needs. As email marketing strategies evolve into 2026 and beyond, marketers who focus on relevance, intent, and timing will be better positioned than those relying on volume alone.
