133x more volume in nine days. Delivery never dropped below 95%.
A new sending domain is a fast track to the spam folder. Blast your full list on Day 1 and Gmail and Outlook read it as bot-like activity. You get bulk folder placement, possible blacklisting and a spam profile that is slow and expensive to fix.
For Infusion Blends, a gourmet food brand from Georgia, USA, we took the opposite route:
- Cleaned the list first with bulk verification and suppressed every undeliverable profile
- Segmented subscribers by inbox provider: Gmail, Yahoo, Outlook, Apple Mail and others
- Built one on-brand campaign from offers already live on their site
- Set up nine Klaviyo segments, one for each day of the ramp
- Monitored delivery, bounce, spam and unsubscribes every single day
The result: daily volume reached 133x the Day 1 level. Delivery stayed between 95% and 100% every day, and above 98% from Day 4 onward. Spam complaints never went above 0.2%.
The key lesson is that deliverability compounds. Every clean day raises the ceiling for the next one. Infusion Blends can now run a regular cadence of promotions, launches and flows with predictable inbox placement.
Launching on a new domain? Warm it up before you scale.
