Top 5 Affiliate Software Tools in 2026 for Marketers
Affiliate software tools make all the difference to a sophisticated, efficient and profitable affiliate marketing program. We explore the top five in this article.
Not every affiliate program lets anyone join. Many ask prospective partners to apply first, then review each application before handing out an affiliate link. The application is where the program learns who the partner is, where they plan to promote, and whether they are a fit for the brand.
Open enrollment gets you more affiliates. Screening gets you better ones. Programs add an application step for a few reasons:
Keep it short. A good application collects only what you need to make a decision:
Anything beyond that lowers completion. If you need tax details or payout information, collect them after approval during affiliate onboarding.
Once submitted, an application sits in a pending state. The program owner or affiliate manager reviews it and either approves the applicant, which unlocks their links and portal, or rejects them with a short reason. Some programs auto-approve every application and simply keep the answers on file, which gives them the information without the delay.
Programs can also skip the form entirely for partners they already know. A direct invite enrolls a trusted partner without an application.
| Open enrollment | Application-based | |
|---|---|---|
| Who gets in | Anyone who signs up | Applicants you approve |
| Speed to first promotion | Immediate | After review |
| Partner quality | Mixed | Higher, more consistent |
| Best for | Consumer products, large audiences | B2B, regulated, premium brands |
GrowSurf lets you choose how affiliates enroll in each program: open enrollment, where anyone joins instantly, review with manual approval, where you approve each application, or review with automatic approval, where applications are accepted on the spot but the answers are kept on file.
Applicants apply from your hosted affiliate program homepage through a short, one-question-at-a-time form with a review step before they submit. A half-finished application is saved as a draft. You review each application from your dashboard, approve or reject it, and GrowSurf emails the applicant your decision. Approved affiliates get their tracking links and portal access right away. For partners you already trust, send an enrollment invite that skips the application entirely. Applications can also be listed and managed through the REST API.
Name, contact details, where the applicant will promote you, roughly how large their audience is, and how they plan to promote. Ask for agreement to your terms. Leave tax and payout details for onboarding after approval.
No. Approve partners whose audience overlaps with your customers and whose content you would be comfortable putting your name on. Reject coupon-only sites, empty accounts, and applicants who cannot describe how they will promote you.
Aim for two to three business days. Applicants who hear nothing for weeks assume the program is dead and move on.
Open enrollment lets anyone join and start promoting immediately. An application-based program makes people apply first and only activates the ones you approve. Open enrollment maximizes reach; applications maximize partner quality.
Set up your refer a friend program with customer referral and affiliate program software that lowers your acquisition costs, increases customer loyalty, and saves you gobs of time.
Trusted by marketing and product teams that grow through customer, user, and partner referrals.
