What is email marketing software?

Email marketing software lets businesses design, send, and track email campaigns to a list of subscribers. It typically includes templates, list management, automation, and analytics for open and click rates.

How much does email software cost?

Pricing varies widely. Most platforms offer free tiers for small lists under 500 contacts, starter plans around $20-$50 per month, and enterprise tiers that scale into hundreds or thousands of dollars based on subscriber count or send volume.

What is the difference between marketing email and transactional email?

Marketing email is sent to promote products, content, or offers and requires opt-in consent. Transactional email is triggered by a user action, such as order confirmations, password resets, or receipts, and is usually sent via a separate API-based service for reliability.
