ActiveCampaign is the pick if you need serious automation depth, a built-in CRM, and lead scoring across any industry. It starts at $15/mo for basic email but you will need the $49/mo Plus plan to get the features that justify the switch. Omnisend starts free and delivers e-commerce-specific automation, SMS, and web push in one place at a price that does not punish small stores. If you run a Shopify or WooCommerce store and want multi-channel campaigns without a steep learning curve, Omnisend wins on value and speed.

Both tools price by contact count, but they scale very differently. Here is what you actually pay at each stage of growth.

ActiveCampaign’s automation builder is the best in its class for non-enterprise tools. You get conditional branching, goal steps, split testing within automations, and the ability to trigger sequences based on CRM deal stage, site visits, or custom events. Omnisend has solid pre-built e-commerce workflows like abandoned cart, browse abandonment, and post-purchase sequences, but its automation logic is shallower. You cannot build the kind of multi-path, behavior-triggered journeys in Omnisend that ActiveCampaign handles natively. For any business that needs marketing automation beyond e-commerce lifecycle emails, ActiveCampaign wins this category without much contest.

Omnisend was built specifically for e-commerce and it shows. Native Shopify and WooCommerce integrations sync product data directly into campaigns, letting you insert live product blocks, discount codes, and order data in minutes. Omnisend also combines email, SMS, and web push in a single workflow at no extra platform fee, with SMS credits included in paid plans. ActiveCampaign integrates with e-commerce platforms but requires more setup, and SMS is available only as an add-on at additional cost. If your entire marketing goal is to drive more revenue from an online store, Omnisend is the faster, cheaper path.

ActiveCampaign includes a built-in CRM with pipeline management, lead scoring, and deal automation starting on its Plus plan at $49/mo. This makes it a genuine all-in-one for small B2B teams who do not want to pay separately for a CRM and email tool. Omnisend has no CRM, no lead scoring, and no pipeline features. It is purely a marketing channel tool for consumer-facing businesses. If you are in SaaS, consulting, agencies, or any B2B model where you need to track contacts through a sales process, Omnisend is simply not built for that job. ActiveCampaign is the only real choice in this scenario.

ActiveCampaign’s entry price looks reasonable at $15 per month, but the features that make it worth choosing over cheaper tools sit behind the $49 per month Plus plan, which adds CRM, lead scoring, and conditional content. Omnisend’s free tier supports up to 250 contacts with email, SMS credits, and web push included, and its paid plans start at $16 per month with no feature gating that forces an immediate upgrade. For a Shopify store scaling from 500 to 5,000 contacts, Omnisend keeps costs predictable and the feature set intact without surprise tier jumps. ActiveCampaign’s pricing scales by contact count and plan tier simultaneously, which means a mid-sized B2B team can hit $100 or more per month before unlocking the full automation suite. Omnisend wins this dimension because small and mid-sized e-commerce businesses get more usable features per dollar at every growth stage, and the free plan alone outperforms most entry-level email tools.
