How to Choose the Right Marketing Software

Key factors to evaluate when comparing marketing tools for your team.

Email Deliverability

The most critical factor — poor deliverability sends campaigns to spam regardless of content quality. Look for platforms with strong sender reputations and dedicated IP options.

Automation & Workflows

Visual workflow builders for drip sequences, abandoned cart flows, welcome series, and triggered emails are essential for scalable email marketing.

List Segmentation

Segmenting subscribers by behaviour, purchase history, engagement level, and custom properties is critical for personalised, high-performing campaigns.

Template Library & Editor

A drag-and-drop email editor with mobile-responsive templates saves design time. Check how far templates can be customised to match your brand.

Analytics & Reporting

Open rates, click rates, unsubscribes, and revenue attribution help you understand what's working and continuously optimise.

Integrations & API

Connections to your e-commerce platform, CRM, landing page tool, and analytics stack are necessary for a cohesive marketing operation.
