lemlist

lemlist is an email outreach platform that lets sales and marketing teams send personalized cold emails, automate follow-ups, and run multi-channel campaigns. Teams use it to book meetings, nurture leads, and track campaign performance across the full outreach cycle.

This app connects your lemlist account to Attio so you can manage outreach directly from your CRM. Add leads to campaigns, track activity, and keep your contact records in sync — without switching tabs.

Add lemlist to your workflows and record pages. When the integration is connected, you can act on contacts in Attio and push them straight into lemlist.

Here's what you can do from Attio:

• Add to campaign. Push a contact as a lead into any of your lemlist campaigns.
• Bulk add to campaign. Select multiple records and add them all at once.
• Open in lemlist. Jump directly to a contact's lemlist profile.
• Find email. Automatically find a verified email when adding a lead.
• Find phone. Find a phone number for the lead.
• Verify email. Run email verification via Debounce before adding.
• Deduplicate. Skip adding a lead if their email already exists in another campaign.
• Social enrichment. Trigger LinkedIn enrichment when adding a lead.
