MailPoet vs Omnisend vs DoubleScale: Omnichannel Marketing for WooCommerce Compared

“Omnichannel” is Omnisend’s whole pitch: email, SMS and web push in one workflow for online stores. MailPoet keeps things simpler, email only, inside WooCommerce. DoubleScale, which we build, adds SMS and WhatsApp to a CRM that also lives inside WordPress.

For a WooCommerce store choosing between them, the questions are which channels you will really use, where you want customer data to live, and what you will pay as your customer list grows.

Full disclosure: we make DoubleScale. We have kept the two other tools’ strengths in, quoted every price from their own pricing pages, and listed the cases where DoubleScale is the wrong choice.

This MailPoet vs Omnisend vs DoubleScale comparison covers the channels, the automation and the cost.

Switching from Omnisend to DoubleScale

1. Install DoubleScale and connect an email provider, plus Twilio or the WhatsApp Business API for messaging.
2. Import WooCommerce customers directly.
3. Rebuild cart recovery and post-purchase workflows, adding SMS or WhatsApp where it helps.
4. Keep only contacts with consent for each channel; DoubleScale records opt-outs per channel.

When DoubleScale is not the answer

• There is no built-in sending service. You connect your own provider (Amazon SES, Brevo, Mailgun, SendGrid, Postmark and more) and add its DNS records once.
• No A/B testing yet.
• We are new on WordPress.org, so there are fewer tutorials and community answers than for the big names.
• Automations that send email, sequences, automated campaigns, WooCommerce triggers, SMS and WhatsApp need a Pro plan (from $99 a year). The free automation builder handles tags, lists and contact updates.
• If web push notifications are central to your marketing, Omnisend includes them; DoubleScale does not.
