Spling email proofreader

Proofread your Marketo emails automatically with Spling

Marketo powers some of the most complex B2B email programs in the world. Spling makes sure the content inside them is always error-free.

Marketo runs your nurture programs. Spling keeps the content clean.

Adobe Marketo Engage is the platform of choice for B2B marketing teams managing sophisticated multi-step campaigns, lead nurture flows, and account-based marketing programs. With that complexity comes real content risk: a typo in a nurture email, a grammar issue in a lead scoring trigger, or a localization error in a token-personalized template can quietly undermine campaigns that took weeks to build. Spling fits into your existing test send workflow and catches content issues automatically, before anything goes live.

How it works with Marketo

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

No Marketo integration. No Adobe Experience Cloud setup. Works with any Marketo email type.

Where content quality slips in B2B programs

B2B marketing teams using Marketo tend to focus on lead scoring, segmentation, and pipeline impact. Content QA is rarely anyone's dedicated responsibility. Common problem areas include:

  • Long-running nurture sequences built once and rarely reviewed again
  • Token-personalized templates where dynamic content makes manual proofreading difficult
  • Global teams adapting centrally built campaigns for regional audiences, introducing localization errors
  • Large program libraries where old templates stay active long after the team that built them has moved on

Spling checks every test send automatically, so content quality doesn't depend on whoever has time to review that week.

Built for marketing operations teams

Route proofreading results to any inbox, whether that's a dedicated MOps address, a shared team inbox, or individual campaign owners. No Marketo access required to receive or act on results.
