Sender Review 2026: Generous Free Plan, Real Automation?

Sender (sender.net) is the budget platform most comparison lists skip - and quietly one of the best free plans in email marketing. Automation included at $0 is its killer feature.

Sender Overview

Sender covers the essentials: drag-and-drop email builder, visual automation, SMS campaigns, popups/forms, and transactional email. The pitch is simple - real marketing automation at a price point where competitors only offer newsletters.

What you get:

• Visual email builder + templates
• Automation workflows (even on free plan)
• SMS campaigns and transactional email
• Signup forms and exit-intent popups
• Segmentation and basic e-commerce tracking
• WordPress, WooCommerce, Shopify integrations

The Free Plan

Sender's free tier historically covers up to 2,500 subscribers and ~15,000 emails/month - with automation included. That combination is rare:

• Brevo free: unlimited contacts but only 300 emails/day, no automation
• Mailchimp free: 500 contacts, no automation
• MailerLite free: automation included but lower send caps

For a new store or list under ~2K contacts, Sender's free plan is arguably the strongest starting point in the category. Verify current limits - free tiers shrink over time (Mailchimp and MailerLite both cut theirs recently).

Automation Capabilities

The workflow builder handles the SMB essentials:

• Triggers: list join, tag added, date field, purchase, email engagement
• Pre-built recipes: welcome, abandoned cart, order follow-up, re-engagement
• Branching: basic if/else conditions on subscriber data and behavior

It is not ActiveCampaign - no lead scoring, no site tracking, no CRM pipeline. But at this price, "good enough automation" is exactly the point.

Sender vs Competitors

vs Moosend: Moosend has no free plan but unlimited sends on paid; Sender's free tier wins for starting out.

vs GetResponse: not the same league on features (webinars, funnels, AI, deliverability infrastructure) but roughly half the price. If automation drives revenue, GetResponse is the upgrade path.

Verdict

Choose Sender if: you need real automation at $0 or near-$0, and your stack is simple (WordPress/WooCommerce/Shopify).

Look elsewhere if: you need deep integrations, advanced segmentation, SMS-heavy campaigns, or will scale past ~20K contacts quickly.
