Boostmail vs Omnisend
Boostmail and Omnisend pull in different directions. Omnisend, rated 4.7★ across 3,179 Shopify reviews, is an email and SMS app best known for its deep library of pre-built automation templates, and it prices by contact count. Boostmail is email only and never charges per contact: you pay only for the emails you send, and the first 20,000 every 30 days are free. A list of 10,000 contacts receiving 4 emails each per 30 days costs $15 on Boostmail, where Omnisend's Standard plan for 10,000 contacts is roughly $132/mo.
This comparison lays out that trade honestly. Boostmail's advantages are its price model (keep every subscriber, pay only for what you send, instead of costs that step up each time you cross a contact threshold), two-way Shopify customer and consent sync, abandoned cart reminders with revenue attribution, and coupons captured in BoostPop (our separate popup app) feeding straight into Boostmail. Omnisend's edge is breadth: SMS, and the polish and depth of its automation templates. Every Omnisend figure below is sourced from its own Shopify App Store listing and pricing page, dated, and any criticism is quoted verbatim from real merchant reviews, never asserted by us.

Pricing: pay per send vs pay per contact
The two apps price on different units. Boostmail charges for emails sent: the first 20,000 every 30 days are free, then you pay per 1,000 emails, and there is no charge per contact. Omnisend charges by contact count, and its tiers step up as your list grows; one reviewer quoted below notes that costs can jump at a new contact tier even when sending volume is low.
Boostmail, pay per send
The first 20,000 emails every 30 days are free, with no charge per contact. The example lists below assume each contact receives 4 emails per 30 days.
- 1,000 contacts (4,000 emails) $0
- 5,000 contacts (20,000 emails) $0
- 10,000 contacts (40,000 emails) $15
- 25,000 contacts (100,000 emails) $45
- 50,000 contacts (200,000 emails) $95
- 100,000 contacts (400,000 emails) $210
Prices are per 30-day billing period. Sending more or less often changes the price; list size alone does not. See full pricing for the per-1,000 rates.

Where they overlap, and where they don't
Both apps cover the core of Shopify email marketing: campaigns built in a drag-and-drop editor, segmentation, welcome and abandoned cart emails, and authenticated sending. Beyond that core, Omnisend does more, including SMS and a large library of automation templates. Boostmail's case rests on its price model and a simple, tight Shopify fit.
What both do well
- Email campaigns with a drag-and-drop editor
- Welcome and abandoned cart emails
- Segmentation by engagement, purchase history, tags and location
- Sending-domain authentication (SPF, DKIM, DMARC) and bounce handling (details)
Why merchants pick Boostmail
- No per-contact charge, you pay only for emails sent, and the first 20,000 every 30 days are free
- Simple triggered campaigns, welcome, abandoned cart (up to 3 reminders per cart, with orders attributed back to the campaign) and coupon reminder
- Tight Shopify fit, customers and email consent sync both ways, and coupons captured in BoostPop feed straight in
Where Omnisend leads (the honest gap)
- SMS, Omnisend sends texts alongside email; Boostmail is email only
- Automation templates, a deep, polished library of ready-made workflows across cart recovery, browse abandonment and more
- Large, mature review base, 3,179 reviews at 4.7★ reflect a long track record

Support & reliability
Omnisend's overall rating is high at 4.7★ from 3,179 reviews, and most merchants are satisfied. Two themes still recur in recent reviews worth weighing before you commit. These are verbatim merchant quotes from Omnisend's own App Store reviews, not our characterization.
"Costs jump significantly once you cross a contact tier even if your sending volume is low."
"Support response times can be slow when you hit a deliverability issue."
For Boostmail's side, reliability starts with the basics done properly: you send from your own authenticated domain (SPF, DKIM, DMARC), bounces and complaints are handled and suppressed automatically, and every subscriber gets one-click unsubscribe. Support is handled directly by the team behind the app at the help center.
When to choose which
Neither app is the right answer for every store. Here is the honest split.
Choose Boostmail if…
- You want to keep every subscriber and pay only for the emails you send, not contact-tier step-ups.
- Your core needs are campaigns, a welcome email and abandoned cart reminders, and you do not need a large automation template library.
- You want Shopify customers and email consent kept in sync both ways, and you use (or plan to use) BoostPop to capture coupons and subscribers.
- You market by email only and do not need SMS or AI copywriting.
Choose Omnisend if…
- A deep, polished library of pre-built SMS and email automation templates is central to your workflow.
- You want to launch multi-step, multi-channel sequences from templates with minimal setup.
- SMS-heavy campaigns with bundled credits at higher tiers fit how you sell.
- A long track record and a very large review base weigh heavily in your decision.
If that is you, Omnisend is a strong, well-reviewed choice. This comparison is independent, and we say so plainly.
Frequently asked questions
- Is Boostmail cheaper than Omnisend?
- For most lists, yes, because Boostmail never charges per contact. The first 20,000 emails every 30 days are free, then you pay per 1,000 emails sent. With each contact receiving 4 emails per 30 days, 1,000 contacts cost $0 on Boostmail, 10,000 contacts cost $15, and 50,000 contacts cost $95. Omnisend's Standard plan runs roughly $20/mo at 1,000 contacts and $132/mo at 10,000, and about $413/mo at 50,000, scaling with your contact count. Your Boostmail cost rises with how often you send, so use the calculator on this page with your own numbers.
- Does Boostmail have AI writing tools like Omnisend?
- No. Boostmail has no AI features. You write campaigns yourself in the drag-and-drop editor, starting from a preset template (New Arrivals, Black Friday, Flash Sale and others) if you like. Omnisend's listing includes some AI assistance, so if AI-generated copy matters to you, that is a point for Omnisend.
- What does Omnisend do better than Boostmail?
- Omnisend covers more channels and more automation. It offers SMS alongside email, and a deep library of pre-built automation workflows for cart recovery, browse abandonment and more. Boostmail is email only, and its automations are three triggered campaigns: welcome, abandoned cart (up to 3 reminders, with revenue attribution) and coupon reminder. If you want to launch multi-step, multi-channel automations from templates, Omnisend is the stronger choice.
- Does Boostmail send SMS?
- No. Boostmail is email only. Omnisend offers SMS alongside email, and its higher tiers bundle SMS credits. If SMS matters to how you sell, Omnisend covers it and Boostmail does not.
- How hard is it to switch from Omnisend to Boostmail?
- For most stores it is straightforward. Boostmail syncs your Shopify customers and their email marketing consent in both directions, and you can import any other subscribers from a CSV exported from Omnisend. Then set up your welcome and abandoned cart campaigns and authenticate your sending domain with SPF, DKIM, and DMARC. Omnisend workflows beyond those, such as browse abandonment or post-purchase sequences, have no direct equivalent in Boostmail, so check which ones you rely on first. Boostmail installs free from the Shopify App Store, so you can set it up in parallel and switch over once it is ready.
