Overview
Shopify Email is free and basic. Sender is a budget email and SMS platform with a generous free tier. For stores that want to step up from Shopify Email without jumping to enterprise pricing, Sender is a solid option alongside Sequenzy and Omnisend.
Sender's free tier (2,500 subscribers, 15,000 emails) lets you test the platform fully before paying. The paid plans at $29/month include SMS and better automation than Shopify Email.
Sender's Generous Free Tier as a Testing Ground
Sender offers 2,500 subscribers and 15,000 emails per month on its free plan — significantly more capable than Shopify Email's 10,000 free emails with minimal features. The free tier includes automation, popup forms, and SMS capabilities that Shopify Email lacks entirely. For stores wanting to test real email marketing without commitment, Sender's free plan provides more room to experiment than Shopify Email's bare-bones offering.
The transition from Sender's free tier to paid plans is smooth — $29/month unlocks advanced automation, removes branding, and increases sending limits. This incremental upgrade path is less jarring than jumping from Shopify Email's free tier directly to Klaviyo's $150/month. For budget-conscious merchants who want to grow into a full email platform gradually, Sender provides a gentler cost curve.
The SMS Addition That Separates Sender From Shopify Email
Sender includes SMS marketing alongside email on paid plans. Shopify Email is email-only. For stores where mobile shopping drives significant traffic, SMS follow-ups capture attention that email alone misses. An abandoned cart SMS reminder typically has higher open and response rates than the equivalent email because text messages demand more immediate attention.
The cost-effectiveness of SMS depends on your customer geography and average order value. Domestic SMS is cheap; international messages are expensive. For US-based stores selling products above $40 average order value, SMS abandoned cart reminders consistently show positive ROI. For stores with lower AOV or heavily international customer bases, the per-message cost may not justify the revenue recovered.
Neither Budget Tool Handles Software Subscription Businesses
Both Shopify Email and Sender are built for product commerce — physical goods, one-time purchases, and e-commerce workflows. Neither handles recurring subscription billing, trial management, or transactional email for software applications. SaaS companies evaluating budget email tools need a different category entirely.
Sequenzy at $49/month provides marketing campaigns and transactional email with native Stripe integration. Subscription lifecycle events — trial expiration, payment failure, plan upgrades — drive email sequences automatically. For software businesses, purpose-built subscription tools replace the need for e-commerce-focused budget email platforms.
