Smartlead

Smartlead is a cold email platform centered on deliverability: automatic sending account rotation, unlimited address warmup, multi-channel sequences, unified inbox and reply tracking. All plans include unlimited connected email accounts, distinguishing it from competitors charged per mailbox. The published monthly grid starts at $39/month (2,000 contacts, 6,000 sends), then $94/month (30,000 contacts, 90,000 sends), $174/month (unlimited contacts, 150,000 sends) and $379/month (500,000 sends, 3 SmartServers). Annual billing deducts 17%. Add-ons are billed separately: SmartSenders ($3.99 to $9/month per mailbox), SmartDelivery ($49 to $599/month) and address verification.

The interface and site stay in English, with no announced French version. The editor publishes a data processing agreement in its footer but does not highlight European hosting, meriting verification if you handle large European prospect lists. A documented public API and webhooks let you plug Smartlead into Zapier, Make, n8n, HubSpot or Clay, making it an easy send brick to automate into an existing chain. The limits to know: Smartlead does not supply contact data, you need an external source; cold email prospecting remains legally bounded in Europe and engages the sender's liability; and option stacking can significantly inflate the published price.
