Growing an email list is easy. Growing it without hurting deliverability is the hard part — especially when monthly volume crosses six figures.
Warm up new segments gradually
When you import contacts or launch a new acquisition channel, introduce them to your sending schedule in batches. Sudden spikes to large cold lists are the fastest path to spam folders.
Segment before you scale
Break your base by engagement, purchase history, and category interest. Klivvo syncs store events so you can exclude inactive profiles and prioritize buyers with the highest predicted LTV.
Automate hygiene continuously
Suppress hard bounces, sunset unengaged contacts, and refresh consent records. At 200k sends per month, small deliverability gains compound into meaningful revenue protection.
