Overview

Attentive and Sendlane both serve e-commerce brands with email and SMS marketing, but they approach the market differently. Attentive is the established enterprise leader in SMS marketing with AI-powered conversational messaging and contract-based pricing. Sendlane is a growing challenger offering email and SMS automation with a distinctive send-based pricing model that appeals to mid-market stores.

For brands evaluating their marketing stack, this comparison highlights the tradeoffs between enterprise SMS specialization and accessible, all-in-one email and SMS automation.

Pricing Models Compared

The pricing difference between these platforms is one of the most significant factors. Sendlane charges based on email volume — $100/month for 50,000 sends with unlimited contacts stored. This means you pay for what you use rather than the size of your list. SMS starts at $50/month additional.

Attentive charges per contact for email ($150+ at 10K contacts), plus separate per-message SMS charges at roughly $0.01 each, a $300+ monthly platform fee, and quarterly minimums of $2,000-$3,000. For a mid-market store with 30,000 contacts sending 100,000 emails plus 10,000 texts per month, Sendlane might cost $200-$250 while Attentive could exceed $1,000.

Email Automation Capabilities

Sendlane's email automation builder is more developed than Attentive's. Its pre-built e-commerce workflows cover abandoned carts, post-purchase sequences, win-back campaigns, and browse abandonment with behavioral triggers. The platform also incorporates machine learning insights to optimize send times and content.

Attentive's email was added after its SMS platform and the automation tools reflect this. For email-first marketing strategies with sophisticated multi-step workflows, Sendlane offers more depth and flexibility than Attentive.

SMS Marketing: The Enterprise Gap

Attentive's SMS features remain a generation ahead. AI Concierge enables genuine two-way conversations at scale, RCS messaging brings rich media to texts, and enterprise compliance tools handle quiet hours and opt-out management automatically. These features drive real revenue for large retailers.

Sendlane's SMS handles campaigns and basic automations within email workflows. It covers the essentials — cart abandonment texts, promotional campaigns, welcome messages — but lacks the conversational AI and rich messaging that defines Attentive's platform. For most mid-market stores, Sendlane's SMS is sufficient.

Who Should Choose Which

Choose Attentive if your store generates significant revenue through SMS and you need enterprise-grade messaging tools. Brands sending millions of texts monthly with dedicated SMS teams are Attentive's ideal customers.

Choose Sendlane if you want strong email + SMS automation at a transparent, predictable price. The send-based pricing model is particularly attractive for brands with large contact lists where not every subscriber receives every campaign. Sendlane offers the best value for mid-market e-commerce brands wanting both channels without enterprise commitments.
