FAQ ?
1) What is the best email marketing software for a small business in 2026?

4) What integrations matter most?
Forms/landing pages, ecommerce platform (if you sell), analytics, and CRM (if you do lead sales).
5) How many emails should a small business send per week?
Start with 1–2 emails/week, then increase as long as your engagement stays healthy.
