Picking an email tool
📖 3 min readUpdated 2026-04-19
Each email tool is strong for specific use cases. Mismatch = frustration + cost.
Decision tree
- DTC e-commerce with Shopify: Klaviyo
- Newsletter / creator: ConvertKit or Beehiiv
- B2B SaaS with product events: Customer.io or Braze
- Broad small biz: Mailchimp or MailerLite
- Enterprise marketing: Marketo, HubSpot, Iterable
Migration is annoying but possible
Don't panic-pick. Plan for one migration over the business lifecycle.
Avoid
Using 'the one I already have' when it doesn't fit your use case.
What to do with this
- Match the tool to your business type, not your team's existing tool familiarity, the migration cost pays back fast
- Don't pay for enterprise tools at SMB scale, Marketo complexity wastes time at 5K subscribers
- Audit tool fit annually, as your business evolves the right tool changes, staying on the wrong tool is a tax
- When comparing tools, weight deliverability + flow engine over feature count, features you don't use are just invoice inflation
- Get a real migration quote from current vendor before committing long-term, switching costs are often cheaper than staying
