Send through your own email platform to the test addresses and inspect each mailbox result.

Help your audience warm up a sender.
Show marketers how to connect their own sending provider, choose a gradual sending schedule and follow delivery activity over time. MailSlurp's email warmup supports new senders and reputation recovery, alongside authentication checks and permissioned email.
Start with the email warmup product and setup walkthrough. Ask Kipling for a recording plan and demo allowance before connecting a sender. Show observed results and the time elapsed; warmup does not guarantee inbox placement.

How does commission work?
Earn 30% on the first 3 eligible payments within 6 months of their first payment from customers you refer. Your referral must become a paying customer; free signups alone do not earn commission.
Eligible payments include subscription and usage charges actually paid after discounts. Usage-only payments count toward the payment cap; an annual invoice counts as one payment.
The attribution window is 60 days. Refunds and chargebacks are deducted. Commissions mature after 45 days. New creator payouts are reviewed monthly, with a EUR50 minimum. We confirm eligible purchases, attribution and the full terms when approving your partnership.
Who can partner with MailSlurp?
Creators, educators, publishers, consultants and agencies with an audience interested in email marketing, ecommerce, deliverability or software testing. A focused audience and a useful demonstration matter more than a large follower count.
What comes in a promotion pack?
Each PDF explains the product, walks through a demo and includes a video plan, tutorial links and commission details. The ZIP adds logos, a demo preview and a sample campaign or Playwright example. Email kipling@mailslurp.dev for a free demo account and help with your recording.
How do demo and customer coupons work?
Start by emailing Kipling with an introduction and your content ideas. We'll arrange free demo access or a coupon for the features you want to demonstrate, then help you create your account and get started.
We can also arrange a coupon for your customers with referral tracking. We'll confirm its discount, validity and commission terms with you before it goes into your content.
Can we plan a sponsored demo or guest article?
Yes. Share the format, audience, deliverables and proposed terms. We'll discuss the scope with you before making a commitment. Please clearly disclose sponsorships and affiliate relationships in your content.
Got an audience?
Let's make something useful.
Apply with your channel, audience, two examples of your work and a MailSlurp demo idea. Kipling reviews every application personally. Once approved, we'll agree your terms, arrange free demo access and help you prepare your content.
