Cheapest Shopify email marketing app in 2026: ranked by real monthly cost
The cheapest Shopify email marketing app is not the one with the lowest number on its pricing page, and the listicles that answer this question by copying entry prices lead you into exactly the trap the vendors set. Here is the honest answer up front: the cheapest option that actually works for a new or small store is free - Shopify's native Email app sends 10,000 emails a month at no cost, and Seguno covers a small list for a flat $10/mo. If you want the lowest paid sticker, it runs Seguno ($10), then Brevo ($9 but priced per send with a daily-capped free tier), then Avada and Omnisend ($16), then Mailchimp and Klaviyo ($13 to $20). But the sticker is a decoy. The number that decides your real bill is the cost as your list grows, and the billing traps hidden under the headline. Below we rank by real monthly cost from live App Store ratings and vendor pricing pages (as of July 2026), and we flag every gotcha. We did not install and hands-on test these apps, and we say so.
Lowest paid sticker: Seguno $10/mo, then Brevo $9/mo (but per send, not per contact), then Avada & Omnisend $16/mo.
Cheapest with full email + SMS features: Omnisend or Avada at $16/mo.
Cheapest for a big list emailed rarely: Brevo or Shopify Email (both per send).
The honest caveat: the cheapest entry price is almost never the cheapest at 10,000 contacts. Read the cost-at-scale table before you commit, and mind the billing traps.
The cheapest that works is free (and that is not a gimmick)
Before you pay anyone, know that a new or small Shopify store does not need to. Shopify's own native Email app sends 10,000 emails a month free, then charges a flat $1 per 1,000 emails with no platform fee, and it is already in your admin with nothing to install. For a store with a few hundred subscribers, that is an entire email program at zero cost. If you want a fuller feature set and a subscriber-based flat rate, Seguno covers 250 subscribers with unlimited sends free, then a flat $10/mo, and lives natively inside the Shopify admin. Our best free Shopify email app guide goes deeper on the no-cost route. The point: "cheapest" for most new stores is a rounding error away from free, so do not let a $9 sticker convince you that you must pay.
The cheapest paid apps, ranked by entry sticker
If you do want a paid plan, here is the lowest-sticker order, with the catch attached to each, because every one of these numbers hides an asterisk. Read the model column as carefully as the price.
- Seguno - $10/mo. The lowest honest flat sticker for a Shopify-native email app. Priced per subscriber, email only (SMS is separate), and it scales with your list, so confirm the tier for your subscriber count before you assume it stays $10.
- Brevo - $9/mo. Lower on paper, but Brevo is priced per send, not per contact, and its free plan is 300 emails per day, a daily throttle rather than a monthly pool. Cheap for a big list you email infrequently; awkward for a small list you email often.
- Avada Email - $16/mo. A generous free tier (500 contacts, 12,000 emails a month) and a low paid entry, with email plus SMS. A bootstrapped studio that markets on price.
- Omnisend - $16/mo. Same entry sticker as Avada, but the free plan carries full features including SMS, and it stays cheaper than Klaviyo as you scale. The best value once you outgrow free.
- Mailchimp - $13/mo. Essentials starts at $13, but Mailchimp is not ecommerce-native and its per-contact bill can include unsubscribed contacts unless you archive them.
- Klaviyo - $20/mo. The highest entry here and the priciest at scale, worth it only if you use its data platform. Not a cheap pick, listed so you can see the ceiling.
One name to strike off any "cheap" list: Sendlane. It once read as a mid-priced option, but it has repositioned upmarket toward large-volume senders (effective pricing now runs well into the hundreds per month), so despite older roundups it is not a budget choice for a small store. Verify its current pricing before considering it at all.
Entry price vs cost at 10k: the table that matters
This is the honest twist the vendors bury. The entry sticker and the bill at 10,000 contacts are two different rankings. An app that is cheapest to start can be middling at scale, and a per-send app with a higher sticker can be the cheapest of all for the right sending pattern. The @10k figures below are approximate email-only monthly costs; confirm each on the vendor's live calculator before you commit, since these tiers move and Klaviyo's page is a JavaScript calculator.
| App | Entry price | Cost @10k contacts | Model | Funding |
|---|---|---|---|---|
| Shopify Email | free | ~$0, then $1/1k emails over | per send | Shopify |
| Seguno | $10/mo | scales per subscriber, verify | per subscriber | independent |
| Brevo | $9/mo | by sends, from ~$9 | per send | PE-backed |
| Avada Email | $16/mo | per contact, verify tier | per contact | bootstrapped |
| Omnisend | $16/mo | ~$100/mo | per contact | bootstrapped |
| Mailchimp (Std) | $13/mo | ~$100+/mo | per contact | Intuit |
| Klaviyo | $20/mo | ~$150/mo (verify live) | per contact | public |
Notice the reshuffle. Brevo has the second-lowest sticker but can be the cheapest at 10,000 for a big list emailed rarely, because it charges by sends and not by list size. Omnisend and Avada share a $16 sticker, yet at scale Omnisend runs roughly 35% cheaper than Klaviyo while Klaviyo, the most expensive entry, only widens its lead as the list grows. The cheapest sticker (Brevo at $9, then Seguno at $10) and the cheapest bill at scale are decided by your sending habit, not by the pricing page.
Per contact vs per send: the choice that halves the bill
The single most useful money idea in this category is the pricing model. Most apps charge per contact (Klaviyo, Omnisend, Mailchimp, Avada, Seguno): your bill rises with list size whether or not you email those people, which punishes a big dormant list. A few charge per send (Brevo, Shopify Email native): unlimited stored contacts, you pay per email actually sent, which rewards a large list emailed infrequently and punishes high-frequency senders. Pick the model that matches how you actually send and you can cut the bill in half before comparing a single feature. The full breakdown lives in how much Shopify email marketing really costs.
Per contact
You pay for the list
Bill rises with contacts, sent or not.
Per send
You pay for the sends
Unlimited contacts, pay per email sent.
The traps that quietly raise the "cheap" bill: Brevo's free plan is 300 emails per day, a daily throttle, not a monthly pool. Postscript's "free" Starter needs a roughly $49/mo message minimum, so its SMS is never actually free. Klaviyo bills every active profile since February 2025, not just the ones you email, so the cheap-looking small plan climbs faster than expected. Mailchimp can bill unsubscribed contacts unless you archive them. Omnisend SMS credits expire after 60 days. None are dealbreakers, but none are printed in bold on the pricing page either.
The cheapest picks, in detail
Shopify Email free tier
The native app sends 10,000 emails a month free, then $1 per 1,000, with no platform fee.
Cheapest paid flat sticker
Seguno's flat $10/mo is the lowest honest sticker for a Shopify-native email app.
Email return on spend
Email returns about $36 per $1 spent (Litmus), so the cheapest app that still converts beats the cheapest that does not.
The cheapest sticker is $9. The cheapest bill at 10,000 contacts can belong to a different app entirely. Rank by the curve, not the entry price.MerchantStack cost analysis, July 2026

Frequently asked questions
What is the cheapest Shopify email app overall? For a new or small store it is free: Shopify's native Email app sends 10,000 emails a month at no cost, or Seguno covers a small list for a flat $10/mo. See our best free Shopify email app guide.
What is the cheapest paid Shopify email app? Seguno at $10/mo is the lowest flat sticker, and Brevo is $9/mo but priced per send with a daily-capped free tier. Avada and Omnisend are the cheapest at $16/mo for full email plus SMS.
Is the cheapest app the cheapest at scale? Usually not. The entry sticker and the bill at 10,000 contacts are different rankings. A per-send app can be cheapest for a big list emailed rarely, while a per-contact app is cheaper for a list you email often. See how much Shopify email marketing really costs.
Is Klaviyo ever the cheap choice? No. Klaviyo has the highest entry sticker here and is the priciest at scale, and since February 2025 it bills every active profile, not just the ones you email. It earns its price only when you use its data platform, not as a budget pick.
What about Brevo's free plan? It sends 300 emails per day, which is a daily throttle rather than a monthly pool. Fine for light, steady sending; limiting if you want to blast a campaign to a larger list at once.
Bottom line
Do not confuse the lowest sticker with the lowest bill. If you are new, start free on Shopify's native email app, or pay a flat $10 for Seguno if you want a fuller small-store tool. If you are choosing a paid plan, decide on the pricing model first (per contact or per send), then check your real cost at next year's list size rather than today's entry price, and know the billing traps going in. The cheapest sticker is $9; the cheapest actual bill depends entirely on how you send. Get the model and the scale right and the "which is cheapest" question mostly answers itself.
