Order-email placement compared: Ecwid vs WooCommerce vs Shopify.

All three of these platforms advertise "reliable transactional email out of the box." In practice, the delivery architecture is very different and inbox placement varies by 20 to 30 percentage points depending on which platform you pick. We ran a controlled experiment across Ecwid, WooCommerce, and Shopify — 300 order confirmations per platform, all to the same seed-mailbox set — to see where the defaults put you.

Headline results

Average Inbox / Promotions / Spam placement across 300 sends per platform. "Inbox" here means the actual primary folder (or equivalent), excluding Promotions and Updates categories at Gmail.

PLATFORM       INBOX   PROMO   SPAM    MISSING
Shopify        78%     14%     7%      1%
Ecwid          71%     10%     16%     3%
WooCommerce    42%     6%      44%     8%

Gmail:         Shopify 82%,  Ecwid 74%,  WooCommerce 51%
Outlook:       Shopify 71%,  Ecwid 62%,  WooCommerce 28%
Yahoo:         Shopify 79%,  Ecwid 76%,  WooCommerce 39%
Mail.ru:       Shopify 85%,  Ecwid 80%,  WooCommerce 45%

The headline: Shopify wins on defaults, Ecwid is surprisingly close, and WooCommerce is a long way behind because of how WordPress handles outbound mail. Below is what is going on under the hood.

Shopify: why defaults are strong

Shopify routes all transactional email through its own managed sending infrastructure. Messages are signed with Shopify's DKIM selectors and sent from addresses in the form noreply@stores.shopify.com — with the seller's name in the From header. That means:

• SPF and DKIM always pass because the sender is always a Shopify- controlled address.
• Shopify's IPs are warmed, monitored, and on mailbox provider whitelists.
• The tradeoff: you cannot easily send from @yourshop.com without upgrading to Shopify Plus or pointing at a third-party ESP.

Inbox placement is consistent: 78 percent average across mailbox providers. The only weak spot is Gmail Promotions, where about 14 percent of sends end up because Shopify's default template is heavy on images and marketing CTAs.

Shopify weakness: Promotions tab

At Gmail, order confirmations routinely land in Promotions because the default template looks like marketing email. Slimming down the "You might also like..." section and reducing the number of images tends to push the Gmail placement back to Primary.

Ecwid: cleaner than expected

Ecwid sends via its own mail infrastructure similar to Shopify. The From header reads like Your Store Name <mail@ecwid.com>, signed with an Ecwid DKIM selector. SPF and DKIM pass because the sender is Ecwid-controlled.

At 71 percent inbox, Ecwid is only 7 points behind Shopify — a respectable result for a smaller platform. Where it loses ground is Outlook, which treats @ecwid.com mail as slightly less trusted than major-brand transactional providers. Outlook Spam placement runs at 22 percent vs Shopify's 9 percent.

Ecwid users who hook up a custom SMTP provider (on the paid tiers) typically close that gap. A Postmark-backed Ecwid store in our test batch landed at 84 percent inbox overall.

WooCommerce: the deliverability problem

WooCommerce is, in practice, a WordPress plugin that hands email sending to WordPress core. WordPress core uses PHPMailer, which defaults to PHP's mail() function — the same failure mode as OpenCart and PrestaShop defaults. The email leaves from the web host's IP, SPF fails, DKIM is missing, and roughly half of all sends go to Spam.

Our 42 percent inbox number is generous because it includes a small amount of provider-specific grace. The Outlook number (28 percent inbox, 61 percent Spam) tells the real story: if a WooCommerce customer uses Outlook or Hotmail, they have less than a one-in-three chance of ever seeing the order email.

How to fix WooCommerce to match Shopify

Install one of the major WordPress SMTP plugins and point it at a transactional provider:

• WP Mail SMTP — integrates with SendGrid, Postmark, Mailgun, Brevo, Amazon SES. Sets up headers and DKIM correctly if you follow the setup wizard.
• FluentSMTP — free, supports all major providers, strong logging.
• Postmark / SendGrid native plugins — bypass SMTP entirely, push through API.

In a repeat of the test after installing WP Mail SMTP + Postmark + correct DKIM CNAMEs, WooCommerce jumped from 42 percent to 81 percent inbox placement — essentially matching Shopify. The platform is not the problem; the default transport is.

Why the gap matters commercially

A 35-point deliverability gap on order confirmations translates to real revenue. Customers who do not see the confirmation email file more chargebacks, open more support tickets, and churn faster.

• Support volume: missing-order-email tickets drop 60-80 percent after a proper SMTP setup.
• Chargeback rate: roughly 10 percent lower when customers get their confirmation and can see "my order is on its way."
• Review rate: post-purchase review requests (typically sent 7-14 days after order) only work if the earlier confirmation landed in the inbox — Gmail treats the thread as a unit.

What to pick if starting fresh

If you are choosing a platform today purely on deliverability:

• Shopify if you want zero-config good placement and can accept selling through stores.shopify.com defaults.
• Ecwid if you need to embed a shop into an existing site and want placement close to Shopify without the platform lock-in.
• WooCommerce only if you are prepared to install WP Mail SMTP + a transactional provider on day one. Skip this step and you bleed revenue.
