- SendWILL's free tier covers popups and basic email marketing at no cost, with no required upgrade to get started.
- SendWILL gates custom automation flows behind its $29.90/month Pro plan, so stores needing custom logic pay more than the entry-level Essential tier.
- Privy combines popups with email and SMS automation in one plan, aimed at stores that want to consolidate tools rather than stitch together separate apps.
- OptinMonster focuses purely on popup and on-site form design — it doesn't send email itself, so it's meant to pair with a separate email platform.
- Justuno prices by site traffic rather than contact count, which can get expensive fast for high-traffic, low-conversion stores.
01 Quick Answer: The Best SendWILL Popup Alternative
Privy is the best all-around alternative to SendWILL Popup Email Marketing for most Shopify stores — it pairs popups with real email and SMS automation, including a flow builder that SendWILL only unlocks on its $29.90/month Pro tier. Switching means budgeting for a paid plan from day one rather than starting free. SendWILL (4.9 stars, 7,496 reviews) is still the right call if you're small, want popups plus basic email for free, and don't need advanced segmentation yet. If your priority is deliverability and automation depth at scale, Klaviyo is the better pick; if it's popup design and on-site targeting, look at OptinMonster or Justuno instead.
02 What SendWILL Popup Email Marketing Does Well (and Its Real Limits)
SendWILL earns its 4.9-star rating across 7,496 reviews with a genuinely generous free tier that covers popups and basic email marketing at no cost, plus unlimited popup views and storage. Paid tiers scale to Essential ($11.90/month), Pro ($29.90/month, adds custom automation flows), and Premium ($79.90/month), each with usage-based overage charges once you exceed the plan limit.
The catch is that automation stays "preset" — canned flows, not custom logic — until you reach the Pro tier. That ceiling explains why stores outgrow SendWILL once list size or automation needs increase, even with a strong free-tier starting point.
03 Privy — Best Overall Alternative for Popups + Email/SMS
Privy pairs on-site popups with email and SMS marketing in a single workflow, including a flow builder and audience segmentation rather than SendWILL's preset-only automation. That makes it a natural next step once you've outgrown SendWILL's automation ceiling and want more control without stitching together two separate apps.
- Best for — stores that want popups and email/SMS automation in one app without SendWILL's automation ceiling.
- Trade-off — consolidating popups with email/SMS automation typically costs more than a popups-only free plan, so budget for a paid plan from the start.
04 Klaviyo — Best for Advanced Email/SMS Automation
Klaviyo is one of the more established email and SMS platforms available to Shopify stores, built around deep segmentation, predictive analytics, and send-time optimization — capabilities that go beyond what SendWILL offers even on its Pro tier. It's designed for stores that treat email/SMS as a primary growth channel rather than a popup add-on.
- Best for — stores scaling past a small list that need serious segmentation and predictive send-time tools.
- Trade-off — popups are secondary to email/SMS; less purpose-built for on-site capture design than Privy or Justuno.
05 OptinMonster — Best for High-Converting Popup Design
OptinMonster focuses squarely on popup and on-site form design — templates, targeting rules, and A/B testing — without any email-sending capability of its own. It's built for stores that already have an email platform and just want more sophisticated popup design and testing on the capture side.
- Best for — stores that already have an email platform and just want more sophisticated popup templates and split-testing.
- Trade-off — no email/SMS bundled in, so you'll need to run it alongside a separate email tool, unlike SendWILL's combined approach.
06 Omnisend — Best Free-Tier Email + SMS Combo
Omnisend combines popups with email and SMS marketing in one app, aiming to match SendWILL's free-tier spirit while adding channels SendWILL doesn't bundle for free. Paid plans scale with contact volume and email send limits as your list grows, with SMS generally metered separately.
- Best for — stores that want popups plus email and optional SMS without SendWILL's subscriber-count overage risk.
- Trade-off — SMS is typically pay-as-you-go rather than bundled in, so costs can creep on SMS-heavy campaigns.
07 Justuno — Best for On-Site Conversion + AI Targeting
Justuno leans into on-site conversion tools — visitor identification, personalization, and workflow automation — for stores that want to do more with the traffic they already have. It generally prices by monthly site traffic rather than contact list size, a different cost model worth understanding before comparing against SendWILL's subscriber-based pricing.
- Best for — higher-traffic stores that want AI visitor identification and advanced on-site personalization.
- Trade-off — traffic-based pricing can punish high-traffic, low-conversion stores.

09 Who Should Stick with SendWILL Popup Email Marketing
SendWILL still makes sense for early-stage stores collecting a modest number of subscribers a month that want popups and basic email in one free app. Its free tier is generous by ecommerce popup-app standards, and the $11.90/month Essential plan is an affordable entry point once you outgrow the free tier. The trade-off is automation depth: once you need custom flows rather than presets, you're paying $29.90/month for Pro anyway — at which point it's worth comparing against dedicated email/SMS platforms rather than assuming SendWILL is automatically cheaper.
10 Who This Is For
Store owners actively using or evaluating SendWILL who want a straight comparison of pricing tiers and feature depth before committing budget — not a generic list of every popup app on the Shopify App Store.
11 Conclusion
SendWILL Popup Email Marketing remains a strong free-to-cheap starting point, but Privy is the better overall alternative once you need popups and email/SMS automation working together without hitting SendWILL's preset-flow ceiling. If your list is scaling fast, a dedicated email/SMS platform like Klaviyo is worth evaluating for its automation depth; if popup design or on-site AI targeting matters more than email, OptinMonster and Justuno are worth a look. For most stores ready to move past SendWILL's free tier, Privy is the pick.
