- Deliverability: reputation, authentication support, and list hygiene tools.
- Integrations: WordPress, WooCommerce, Shopify, CRMs, and payment tools.
- Analytics: opens, clicks, conversions, and revenue tracking.

- Monthly or daily email sending limits.
- Automation availability.
- Branding (platform logo in emails).
- Access to templates and landing pages.
- Support availability.
Start free, and upgrade when you need more subscribers, advanced automation, or removal of branding.
Automation features
The automations that matter most for small businesses:
- Welcome sequence: deliver your lead magnet and introduce your business — see Email Marketing 101.
- Nurture sequence: share your best content and build trust.
- Abandoned cart (ecommerce): remind shoppers to complete purchases.
- Post-purchase follow-up: onboarding, review requests, and cross-sells.
- Re-engagement: win back inactive subscribers — or clean them from your list.
- Birthday or anniversary emails.
