FAQ
Frequently asked questions
Yes, AI-optimised subject lines and send times typically improve open rates by 10-25%. Personalisation features can improve reply rates by 2-3x for cold outreach.
AI-powered emails should follow the same rules as any outreach: comply with CAN-SPAM/GDPR, include unsubscribe options, and target relevant recipients. The AI helps with quality and personalisation, not volume.
AI tools analyse recipient data (LinkedIn profiles, company info, recent news) to generate personalised opening lines and content. This goes beyond mail merge to create genuinely relevant messages.
Email warmup gradually builds sending reputation for new email accounts by sending and receiving legitimate emails. Tools like Instantly.ai and Smartlead automate this to improve deliverability.
Most tools integrate with popular CRMs like Salesforce, HubSpot, and Pipedrive. This enables automatic logging of email activity and personalisation based on CRM data.
