Does Smartlead offer a free plan or trial?

Smartlead does not have a permanent free tier, but it offers a 14-day free trial so you can explore the platform before committing to a paid subscription.

What does 'unlimited mailboxes' actually mean?

On all Smartlead plans you can connect as many sending mailboxes as you need — across Gmail, Outlook, and custom SMTP providers — without paying extra per mailbox. This is especially useful for agencies managing multiple client accounts or teams rotating senders to protect deliverability.

What CRMs and tools does Smartlead integrate with?

Smartlead integrates natively with HubSpot, Salesforce, Pipedrive, and Clay, and supports broader automation through Zapier, Make, and N8N. It also exposes a REST API and webhooks for custom integrations.

Is Smartlead suitable for agencies running campaigns for multiple clients?

Yes — Smartlead is specifically designed with agencies in mind. It supports white-label customization, multi-client workspace management, and offers high-volume custom plans, making it a popular choice for lead generation agencies.

How difficult is it to get started with Smartlead?

Smartlead provides a step-by-step campaign creation flow, a help center, and Smartlead University (a free training resource) to guide new users. Basic campaigns can be up and running quickly, though mastering deliverability optimization and AI agent configuration has a moderate learning curve.
