In private development

Stop rebuilding the same campaign three times.

CampGain builds your drip campaign once and delivers it over email, RCS/SMS, and WhatsApp — then handles the replies in a shared inbox and shows you what each step actually earned. Synced to your Shopify store. We’re building it now.

No account, no card. We email you once, when it opens.

“Autumn restock”

One campaign · 3,204 customers

  1. Email SendGrid, Resend, or Gmail

    “The autumn restock is live”

    then wait 2 days

  2. WhatsApp Official Meta Business API

    “Still thinking it over?”

    then wait 1 day

  3. RCS/SMS Twilio, with SMS fallback

    “Last day — 20% off”

One build. Three sends. The waits are handled for you.

What we’re building

Three things, not thirty

Reaching customers, answering them, and knowing what worked — in one place, because splitting them across three tools is what makes each one harder than it should be.
