Stop losing outbound data

"With how bad the native sales engagement platform HubSpot integrations are, I used to spend hours each week tracking down data and convos needed for our GTM team. OutboundSync cut that down to zero minutes a week. We'd send thousands of emails with conversations lost between Hubspot and Smartlead. OutboundSync fixed it. It saved my sanity, which was slowly slipping away with every email we lost."


Review and reply in one place  

Use timeline events in the contact record to see historical events, create lists, trigger workflows, and more. 

Reply to logged emails to continue the conversation, use enablement materials like templates, book a meeting, and close the deal.


Create advanced workflows

Use OutboundSync to create advanced workflows that can update properties, rotate contact owners, create notifications, and much more.

Use specific triggers for data enrichment with tools like Clearbit and Clay. With that new data, go omnichannel inside of HubSpot by phone or LinkedIn.


Turn HubSpot lists into block lists  

Make sure you never email the wrong people. OutboundSync will do an initial pull of your list in HubSpot and then monitor for any changes.

Beyond email addresses, you can block entire domains to ensure that nobody at a company is contacted via cold outbound.


Build native reports and dashboards

Monitor campaign results inside of a HubSpot dashboard so you always know where you stand without jumping to another tool.

Build reports to track things like sending volume, replies, opens, and more on a monthly, weekly, and daily basis.
