If you're leaving Sendlane, start with the flows that make your store money and pick the platform that rebuilds them with the least fuss. For most stores the nearest swap is a platform that runs email and SMS together; pick a design-led email tool only if texts don't matter, and an add-on only if your sender stays.
Switching email platforms is a bigger job than it looks from the outside. Your welcome series, abandoned cart reminders, post-purchase emails and SMS consent records all have to come with you, and a gap of even a few days can show up in your sales. That's why I'd judge every option here on how well it carries your existing flows, not on its homepage.
Who this Sendlane comparison is for
It's written for ecommerce store owners who run email and SMS flows themselves, or with a small team, and who are weighing Sendlane against other platforms. You might be on Shopify or WooCommerce, you probably send a mix of campaigns and automated messages, and you want one less thing to worry about each week. If you're a solo creator sending a newsletter, a simpler email tool will do the job.
Three jobs these platforms do
Email and SMS under one roof. Attentive, Klaviyo, Mailchimp, Omnisend, Postscript and Privy all put both channels in one account, which matters if your flows switch between a text and an email. One of them adds pop-ups for capturing sign-ups, and another also mentions RCS.
Email-led platforms with wider tools. Brevo bundles email and SMS with a CRM, live chat and transactional email. Flodesk leans hard on design, and MailerLite pitches a broader set of marketing tools and says its support runs around the clock.
Add-ons that sit beside your sender. Retention.com supplies person-level identity data to the tools you already run, and Rivo covers loyalty, referrals and memberships for Shopify brands. Neither replaces your email platform; they feed it.

One-click unsubscribe deserves a check
Before you move a list, look at how a platform handles unsubscribes. The IETF published RFC 8058 in 2017 under the title Signaling One-Click Functionality for List Email Headers, so one-click unsubscribe is a written email standard, not a nice extra. Ask any shortlisted platform whether it adds those headers to your campaigns, because an easy way out keeps unhappy subscribers from reaching for the spam button instead.
What to move across before you switch
- Every live flow, written down step by step, with its delays and conditions.
- Your SMS consent records and where each one came from.
- Segments you use often, so you can rebuild them on day one.
- Your best-performing templates, saved as HTML or screenshots.
Run both platforms side by side for a short overlap if you can. It's dull, but it's the easiest way to spot a flow that didn't make the move. If you're tracking the effect on sales, these ecommerce KPIs are the ones to watch in the first few weeks, and if text messages are the bigger part of your plan, my guide to SMS marketing software goes further on that channel.
Still deciding between the two biggest names? Here's how those two email platforms compare head to head.

My advice for store owners leaving Sendlane
Don't choose on features you'll never switch on. List the three flows that bring in most of your email revenue, then ask each vendor to show you those three built in their tool. If SMS matters, check how consent moves across before anything else, because rebuilding a text list from scratch is painful. And if you only need loyalty or identity data, an add-on beside your current sender may save you a full migration.

Frequently asked questions
Is it hard to move from Sendlane to another platform?
It's mostly a matter of rebuilding flows and importing contacts with their consent status. The hard part is remembering every automation you set up, so write them all down before you start and check each one works after the move.
Do I need SMS as well as email?
Not always. If your customers buy often or respond to time-sensitive offers, texts can help. If you sell considered purchases with long gaps between orders, email alone may be enough to start with.
What's the difference between an email platform and a retention add-on?
An email platform sends your campaigns and flows. A retention add-on, such as a loyalty or identity tool, feeds extra data or rewards into that platform but doesn't replace it.
Should I worry about deliverability when I switch?
Yes. Warm up a new sending setup gradually, start with your most engaged subscribers and keep an eye on bounces and complaints for the first few weeks.
How long should I run two platforms at once?
Long enough to see every important flow fire at least once on the new platform. For most stores that's a few weeks, depending on how often customers trigger each flow.
