How do people optimize email outreach with Smartlead AI to increase real reply rates?

Hi everyone,

I just started using Smartlead AI to automate email outreach for B2B campaigns, and I'm really impressed with the ability to manage multiple accounts at the same time, as well as the automatic warm-up system. However, I'm still looking for ways to increase the response rate in cold email campaigns.

I want to ask everyone's experience:

Do people have any effective email content personalization strategies (e.g., using {{first_name}} a separate intro)?

What criteria should I use to segment my contact list to increase message relevance?

Has anyone used AI sequencing or that's not my neighbor automated A/B testing in Smartlead, and how effective are they?

Looking forward to hearing real-life experiences from those who have been using Smartlead for a long time.

I think if we share tips, we can help the community leverage AI to make email marketing more effective and natural.

Thank you all in advance!
