Ecommerce retention lives and dies by list quality. Order exports, marketplace reports, support-ticket threads, and abandoned-cart logs all hold customer addresses, but they arrive full of duplicates, typos, and role addresses like support@ that should never receive a promo. A dirty list tanks deliverability right before a big sale.
This workflow shows how to consolidate customer addresses from every channel, strip out role and disposable addresses, dedupe repeat buyers, and export a clean list your email platform will actually deliver.
The workflow
1
Pull addresses from order and support data
Paste order exports, marketplace reports, and ticket threads into the bulk extractor to collect every customer address.
2
Remove role and disposable addresses
Detect role-based addresses like info@ and drop disposable domains that will bounce or complain.
3
Deduplicate repeat buyers
Merge channels and remove duplicates so loyal customers aren't hit multiple times per send.
4
Export for your ESP
Convert to CSV formatted for Klaviyo, Mailchimp, or your platform of choice.
