What to Look For When Choosing Email Marketing Software
Before you sign up for any tool, run it through these key criteria:
- Ease of Use: You shouldn’t need a developer to send an email. Look for a drag-and-drop email editor, simple list management, and a clean dashboard. If the interface feels clunky during a free trial, it’ll feel worse at 11pm when you’re trying to launch a campaign.
- Automation & Workflows: This is where email marketing gets powerful. A good platform lets you automate welcome sequences, abandoned cart emails, post-purchase follow-ups, and behavior-triggered campaigns without manual effort. Look for a visual automation builder that doesn’t require a degree to use.
- Segmentation & Personalization: Sending the same email to your entire list is outdated. The best platforms let you segment subscribers by behavior (clicks, purchases, page visits), demographics, tags, and custom fields so the right message reaches the right person at the right time.
- Deliverability: A beautiful email means nothing if it lands in spam. Check third-party deliverability scores for any platform you’re considering. Established platforms like AWeber and GetResponse consistently score above average.
- List Size vs. Pricing: Most platforms charge based on the number of subscribers. As your list grows, costs climb fast. Compare pricing tiers at 1K, 5K, 10K, and 25K subscribers not just the entry-level plan before committing.
- Landing Pages & Forms: Growing your list requires opt-in forms and landing pages. Many tools now include a basic landing page builder so you don’t need a separate tool. Assess quality and flexibility before relying on it.
- Integrations: Your email tool needs to talk to your other tools your website, ecommerce store, CRM, course platform, or affiliate software. Check native integrations (not just Zapier workarounds) with the tools you already use.
- A/B Testing: Subject line testing, send-time optimization, and content split testing can meaningfully improve open and click rates. Make sure the platform supports at least basic A/B testing.
- Analytics & Reporting: You need to see open rates, click-through rates, unsubscribes, revenue attributed to campaigns, and ideally which automations are actually converting. Weak reporting = flying blind.
- Compliance (GDPR, CAN-SPAM): With privacy laws tightening globally, your platform must support consent management, unsubscribe handling, and data deletion requests. All five platforms in this guide handle this but always verify for your specific region.
- Customer Support: When something breaks during a launch, you need fast help. Check support hours, channels (live chat vs. email only), and community quality before choosing.
- Affiliate Marketing Policy: Some platforms (like Mailchimp) are notoriously strict and will ban accounts for affiliate links. If affiliate marketing is part of your business, confirm the platform explicitly permits it.
