Popular Use Cases
High-Volume Cold Email Hygiene
When running cold email at scale through Instantly, list quality is everything. Cleanlist verifies every address before upload, keeping your bounce rate under 2% across hundreds of sending accounts and thousands of daily emails.
Lead List Enrichment for Targeting
Enrich sparse lead lists with company size, industry, and job title data before uploading to Instantly. Use enriched fields to split leads into targeted campaign segments for higher reply rates.
Sending Infrastructure Protection
Protect your Instantly sending accounts and domains by routing bounce-risk leads to warm-up accounts or excluding them entirely. Cleanlist's risk scoring prevents the inbox placement drops that kill cold email campaigns.
Frequently Asked Questions
Why should I verify emails before uploading to Instantly?
+
Instantly relies on healthy sending accounts and domains to achieve inbox placement. Uploading unverified leads risks bounces that damage your sender reputation, trigger spam filters, and reduce deliverability across all your campaigns. Cleanlist verification eliminates this risk before leads enter Instantly.
Can Cleanlist handle high-volume lead lists for Instantly campaigns?
+
Yes. Cleanlist bulk verification processes at roughly 1,000 leads per minute, so a list of 50,000 contacts can be verified in under an hour. This makes it practical to verify every lead before every campaign, even at high volume.
Does Cleanlist enrich leads with data I can use for Instantly campaign segmentation?
+
Yes. Cleanlist adds company name, industry, employee count, job title, and other firmographic fields to your leads. You can use these fields to create targeted Instantly campaigns that speak to specific verticals, company sizes, or buyer personas.
How does bounce-risk scoring work?
+
Cleanlist assigns each email a risk score based on verification results, domain reputation, and historical bounce data. You set a threshold in the integration settings, and leads above that threshold are either excluded from campaigns or routed to warm-up accounts to protect your primary sending domains.
