The ad network built for email newsletters

SenderCircle is a performance-based newsletter advertising network that connects independent email newsletter publishers with vetted brand advertisers. Publishers earn revenue from opt-in sponsored placements; advertisers reach engaged, high-intent audiences and pay on CPM, CPC, CPL, CPA, or hybrid terms.

SenderCircle serves two groups: independent email newsletter publishers who want to earn revenue from sponsored placements without doing sales work, and advertisers who want to reach engaged, high-intent professional audiences and pay only for results. Publishers join free and choose which campaigns to run; advertisers get one point of contact for 200+ newsletters.

SenderCircle is a curated, human-managed network, not a programmatic exchange. Every newsletter is vetted before joining, every campaign is reviewed for brand fit, and publishers opt in to each placement individually. Pricing is performance-based (cost per lead, click, or acquisition) rather than impression-based, so advertisers pay for outcomes and publishers with engaged audiences earn more than they would from display ads.

Publishers browse a dashboard of vetted sponsor campaigns, choose the ones that fit their audience, and include them in their regular sends. They are paid per open (CPM), per click (CPC), per lead (CPL), per sale (CPA), or on a hybrid of CPC plus a CPL or CPA bonus. Earnings are tracked in real time and paid out monthly. SenderCircle handles all advertiser relationships, negotiation, and reporting.

Advertisers pay on performance: cost per lead (CPL), cost per click (CPC), cost per acquisition (CPA), or a hybrid model, with fixed-rate sponsorships also available. One agreement gives access to the whole network, and SenderCircle matches each campaign to the newsletters whose audiences are most likely to convert.

As of 2026-09-03, SenderCircle includes 200+ independent newsletters reaching 15M+ subscribers, with an average open rate of 52%+ and an average click rate of 2.7%+. 91% of advertisers renew.

Newsletter publishers create a free account, connect their newsletter, and are typically reviewed within 24-48 hours. Advertisers schedule a short call to discuss goals, and campaign setup typically takes 24-48 hours.
