How to Choose the Right Tool for Your Stack
Selecting a platform is a commitment. Here is a checklist to help you decide:
- Match Features to Goals: Don’t pay for complex automation if you only send a weekly newsletter. Conversely, don’t settle for a basic tool if you need behavioral tracking.
- Scalability Check: Look at the pricing tiers. Some platforms get exponentially more expensive as your list grows—ensure the ROI scales with the cost.
- Audit Integrations: Does the tool play nice with your CRM, website builder, and analytics tools? Native integrations save hours of headaches.
- Prioritize the Inbox: Features mean nothing if you land in spam. Look for platforms with transparent deliverability stats.
- Test the UX: Most platforms offer free trials. Use them to send a test campaign and see how intuitive the workflow feels to you.
