Klaviyo is the best email and SMS marketing platform for most ecommerce brands in 2026. Omnisend is the best pick for small stores on a budget, with a free plan and paid email from $16 a month.
The rest of the list covers narrower needs. Attentive suits large brands that treat text messaging as a main revenue channel. Postscript is built for Shopify stores that want SMS first. Drip fits email-first stores, and Mailchimp works for sellers who want a familiar tool with a free plan.
Before you commit, price your real list, not the entry tier. Almost every platform here charges by contacts or messages sent, so a store with 20,000 subscribers pays far more than the starting price, and SMS carrier fees often sit on top.

3. Attentive
Best for large brands that sell heavily by text
Our rating4.5 / 5
Starting priceCustom pricing
Free planFree trial
Attentive started as an SMS platform and now covers text, email, RCS, and push in one system. It suits established brands that send high message volume and want managed strategy help. Attentive does not publish prices. Its pricing page says channel bundles are priced on list size and messages sent, and a text-only option is billed per message and subscriber. It offers free trials, but expect a sales process and a larger commitment than self-serve tools.
Pros
- Strong SMS tools built for scale
- Text, email, RCS, and push together
- AI features included with every plan
Cons
- No public pricing
- Sales-led setup
- Too much platform for a small store

4. Postscript
Best for Shopify stores that want SMS first
Our rating4.4 / 5
Starting price$49 / month minimum spend
Free planFree trial (30 days)
Postscript is an SMS platform built for Shopify. The Starter plan has no base fee but carries a $49 monthly minimum spend, with SMS at $0.009 per message. Growth costs $100 a month and Professional costs $500 a month, each with lower message rates. Carrier fees are billed on top, and every plan starts with a 30-day free trial. Postscript lists its email product as waitlist only, so you still need a separate email platform for now.

- 30-day free trial on every plan
Cons
- Email product is waitlist only
- Carrier fees billed on top

5. Drip
Best for email-first stores that want simple pricing
Our rating4.2 / 5

Free planFree trial (14 days)
Drip is an email platform aimed at online stores, with visual workflows, segmentation, and revenue reporting. It starts at $39 a month for up to 2,500 people on your list, and the price steps up as the list grows. The 14-day free trial needs no credit card, though unlimited sends are not available until you upgrade. Its pricing page lists email only, so a store that wants texting will need a separate SMS tool.
Pros

Essentials starts at $13 a month and Standard at $20 a month, each with a 14-day trial that requires payment details. SMS is a paid add-on in select countries, and you must apply and be approved before you can buy credits. Its ecommerce automation is lighter than the tools ranked above it.

- Free plan to start
- Connects to many store platforms
Cons
- SMS needs an application and approval

How to choose an email and SMS platform for your store
Price your list as it is today and in a year
Entry prices cover a few hundred contacts. Pull your current subscriber count, add your expected growth, and run both numbers through each vendor’s calculator. A tool that looks cheap at 500 contacts can cost more than a rival at 15,000.
Decide whether you need SMS in the same tool
Klaviyo, Omnisend, Attentive, and Mailchimp handle both channels. Postscript is SMS first and Drip is email only. One platform keeps profiles and reporting together, while two specialist tools can give you deeper features on each channel at the cost of a second bill.
Count every texting cost
SMS pricing has layers: a plan fee or minimum spend, a per-message rate, and carrier fees. MMS costs more than plain text. Ask each vendor what one campaign to your full SMS list would cost before you compare plans.
Check the integration with your store
Most of these tools are built around Shopify first. If you sell on WooCommerce, BigCommerce, or several channels, confirm that order and product data sync in real time, since abandoned cart and post-purchase flows depend on it.
Frequently asked questions
Which email and SMS platform is best for a Shopify store?
Klaviyo is the best fit for most Shopify stores because it uses order and browsing data to power both email and SMS. A smaller store can start on Omnisend for less, and a store that wants texting first can pair Postscript with a separate email tool.
How much does ecommerce email and SMS marketing cost?
Expect to pay from about $13 to $40 a month for email at a small list size, based on published prices from Mailchimp, Omnisend, Klaviyo, and Drip. SMS adds a per-message cost plus carrier fees. Attentive quotes prices on request, and costs at every vendor rise with list size.
Can you start for free?
Yes. Klaviyo, Omnisend, and Mailchimp each offer a free plan for up to 250 contacts with 500 email sends a month. Postscript and Drip offer free trials instead. Free plans suit testing and very small lists, but most growing stores outgrow them within months.
Do you need separate tools for email and SMS?
No. Klaviyo, Omnisend, and Attentive run both channels from one profile, which keeps segments and reporting in one place. Some brands still pair an SMS specialist like Postscript with an email tool because they want deeper texting features. Whichever route you pick, make sure SMS and email subscribers share one consent record.
