Email Proofreader launched with early access pricing

Proofread your Salesforce Marketing Cloud emails automatically with Spling

Enterprise email programs send at massive scale. Spling makes sure every send is error-free, without adding complexity to your workflow.

Spling spell checks entire websites

Salesforce Marketing Cloud is built for enterprise. So is the content risk.

Salesforce Marketing Cloud is used by some of the world's largest organizations to manage complex, high-volume email programs. With that scale comes real stakes: a typo in a campaign going out to a million subscribers, or a grammar issue buried in a Journey Builder automation that no one has reviewed in months. Spling fits quietly into your existing test send workflow and catches content issues before they ship.

How it works with Salesforce Marketing Cloud

  1. Sign up to get your free Spling QA email address.
  2. Add it to your Marketing Cloud test send list in Email Studio.
  3. Spling emails you proofreading results automatically, every time.

No Salesforce integration. No AppExchange install. No admin required.

Where content quality slips in large email programs

Enterprise email teams move fast and manage a lot. Content QA is often the step that gets squeezed. Common problem areas include:

  • Journey Builder automations built months ago that nobody reviews until something goes wrong
  • Dynamic templates with copy that changes across segments, making manual review impractical
  • Large teams with multiple contributors where no single person owns proofreading
  • High send volumes where a single error is multiplied across millions of inboxes

Spling checks every test send automatically, so your QA process doesn't depend on anyone remembering to do it.

Built for teams at scale

Route proofreading results to any inbox — a shared team address, a specific QA reviewer, or both. For large organizations running multiple business units in Marketing Cloud, Spling gives every team its own QA address and its own results.

Conclusion: Salesforce Marketing Cloud plus Spling keeps your content as polished as your campaigns.

Salesforce gives enterprise teams the infrastructure to send at any scale. Spling makes sure the content inside those sends is worth reading. Add your Spling QA address to Email Studio once and error-free email becomes the default across your entire program.
