Our Smartlead integrations focus on campaign-specific lead management rather than global blocklist checking. We offer three main Smartlead actions: "Lookup Lead Status in Campaign" to check if a lead has completed, replied to, exists, or is progressing through a specific campaign, "Lookup Lead in Campaign" to retrieve lead information from a given campaign, and "Add/Remove Lead from Campaign" for lead management.
For email validation and blocklist checking, you might consider our email verification integrations like Hunter, Zero Bounce, or NeverBounce, which can validate email addresses and check various status indicators.
Are you looking to check blocklist status for leads within a specific Smartlead campaign, or do you need general email validation capabilities?
