Outbound Systems Lab is an affiliate-supported publication. We may receive a commission when you visit one of our supported partners through a clearly identified referral link and subsequently sign up or buy a qualifying product or service.
Who we partner with
The publication's supported referral partners at launch are PlusVibe (primary) and Instantly (secondary). Some links lead directly to the partners' sign-up or plan-selection websites.
What this means for your decision
The presence of a referral link does not mean a platform fits every team, is independently tested or guarantees deliverability. We aim to communicate published plan limits, material concerns and the scope of our coverage. This publication is commercially selective and does not claim to be a neutral study of all software vendors.
How you can recognize paid links
Commercial calls to action name the destination product, explain that a commission may be earned, and use a sponsored link attribute. Links to official documentation used as editorial sources are not intended as affiliate conversion links.
Your cost
We do not assert that using an affiliate link raises or lowers your price. Check the merchant's current pricing, taxes, refunds, terms and any promotions directly before purchase.
