Book a DemoSmartSenders is Smartlead's built-in email infrastructure setup feature that lets you purchase domains and mailboxes directly inside the platform. Instead of dealing with multiple providers and manual configurations, you select your domain, choose Google, Outlook, or SMTP mailboxes, and SmartSenders handles the entire setup automatically. All DNS records including SPF, DKIM, and DMARC are configured for you.
SmartSenders currently supports Google, Outlook, and SMTP mailboxes. You can purchase these mailboxes from trusted providers like Zapmail, InfraInbox and Mailreef. Each provider comes pre-configured with authentication records and deliverability best practices. Smartlead has indicated plans to include more email service providers in the future.
No technical knowledge is required. SmartSenders handles the entire infrastructure setup including DNS configuration, mailbox creation, and authentication record setup automatically. MX, SPF, DKIM, and DMARC records are all configured for you.
Mailboxes purchased through SmartSenders are activated within 24 to 48 hours. This window is required for DNS record propagation to complete properly across all email providers. Once activated, mailboxes are connected directly to your Smartlead account and ready for warmup and campaign use.
SmartSenders provides access to pre-vetted vendors and ensures that all technical configurations are handled automatically. It also offers optimized infrastructure for deliverability and removes the need to manage multiple providers separately. Additionally, mailboxes are often available at more competitive pricing compared to traditional resellers.
Yes, standard mailboxes purchased through SmartSenders are new inboxes with no prior sender history, so warmup is required before running campaigns. However, SmartSenders also offers pre-warmed mailboxes through Zapmail that have already completed the warmup process and are ready to send from on the same day, bypassing the typical 2 to 3 week warmup period.
SmartSenders improves deliverability in several ways. Domains come with correctly configured authentication records, high-quality US IPs, and DNS management. Each domain operates in its own isolated workspace, so a reputation issue on one domain does not affect others. You can also diversify sending across Google, Outlook, and SMTP providers within the same campaigns to avoid single-provider dependency and reduce spam triggers.
All DNS records including SPF, DKIM, DMARC, and CNAME records for custom domain tracking are configured automatically when you purchase a domain through SmartSenders. There is no manual input required from the user. This ensures your domains are correctly authenticated from day one and reduces the risk of emails landing in spam due to misconfigured records.
