Treating more rows as progress<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Big lists feel productive until your team spends the week dialing duplicates and wrong-person numbers. Dedupe and validation usually move outcomes faster than adding volume.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"2_No_stable_dedupe_key\"><\/span>2. No stable dedupe key<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>If you dedupe on name plus city, you will double-call physicians and miss merges. Use NPI\/license matching as the backbone, then keep names as display fields only.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"3_Mixing_line_types_in_the_same_block_without_routing_rules\"><\/span>3. Mixing line types in the same block without routing rules<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Office lines and mobile behave differently. Blend them and your Connect Rate per 100 dials becomes hard to interpret, and recruiters lose trust in the queue.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"4_Not_refreshing_after_no-answer_clusters\"><\/span>4. Not refreshing after no-answer clusters<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>When a slice of the list produces repeated no_answer outcomes, don&#8217;t just increase attempts. Refresh validation and\/or swap to a different number for that physician. Phone numbers decay; your process has to assume it will happen.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"5_Building_phone-centric_rows_instead_of_physician-centric_rows\"><\/span>5. Building phone-centric rows instead of physician-centric rows<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>A common mistake: teams build a CSV where each row is &#8220;a phone number&#8221; rather than &#8220;a physician contact attempt.&#8221; That makes it hard to dedupe, hard to suppress correctly, and hard to route by line type. Fix it by making the CSV physician-centric (NPI\/license plus physician_id) and treating phone_number as an attribute with its own validation and line type.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_to_improve_results\"><\/span>How to improve results<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"Build_a_measurement_loop_ops_can_act_on\"><\/span>Build a measurement loop ops can act on<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Run weekly call blocks that are intentionally comparable \u2014 same time window, same routing rules \u2014 then split results by source, line_type, and validation recency.<\/p>\n<ul>\n<li><strong>Connect Rate<\/strong> = connected calls divided by total dials, reported per 100 dials.<\/li>\n<li><strong>Connects per hour<\/strong> = dials per hour multiplied by Connect Rate. Use your own observed dials per hour and your own Connect Rate from comparable call blocks.<\/li>\n<\/ul>\n<p>There&#8217;s no single universal benchmark here, because your baseline depends on mix: line type, specialty, time window, and list hygiene all shift the number. The point is consistency \u2014 comparable call blocks make improvements obvious.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Refresh_triggers_instead_of_fixed_schedules\"><\/span>Refresh triggers instead of fixed schedules<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<ul>\n<li>If a source slice&#8217;s Connect Rate drops across two comparable call blocks, re-validate that slice.<\/li>\n<li>If wrong_person outcomes rise, audit dedupe keys and mapping rules (NPI\/license alignment).<\/li>\n<li>If gatekeeper outcomes dominate, separate office lines into their own call blocks and adjust scripts.<\/li>\n<\/ul>\n<h3><span class=\"ez-toc-section\" id=\"Suppression_and_consent_handling\"><\/span>Suppression and consent handling<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Make opt-out and do_not_contact outcomes irreversible in the workflow. Your list should suppress across all sources and future imports. Track consent signals where applicable, and don&#8217;t re-add suppressed contacts just because a new source file appears.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Make_it_easy_to_start_and_hard_to_break\"><\/span>Make it easy to start and hard to break<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<ul>\n<li>Lock required columns in your CSV template.<\/li>\n<li>Reject imports missing phone_number or opt_out_status; quarantine imports missing NPI\/license or phone_validation fields for cleanup before dialing.<\/li>\n<li>Keep a single owner for list hygiene (ops) and a single owner for outcomes (recruiting).<\/li>\n<\/ul>\n<p>If you want to move fast, you can start free search and preview data \u2014 access plus refresh, verification, and suppression, not a static list \u2014 and then export into the template once your routing fields are in place.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Legal_and_ethical_use\"><\/span>Legal and ethical use<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>This playbook is about legitimate recruiting outreach. Build your process around respect and suppression:<\/p>\n<ul>\n<li>Honor opt-out requests immediately and globally, across all lists and sources.<\/li>\n<li>Be transparent about who you are and why you&#8217;re calling.<\/li>\n<li>Keep notes professional; avoid storing sensitive personal data.<\/li>\n<li>Follow applicable phone\/SMS rules and local data laws.
