Rule of thumb is 4-6 weeks of warm-up, then a slow ramp-up of actual outbound emails, but ChatGPT will give you a more thorough answer 😉

I've never seen an "instant" warmup - in our case it took about 2 months to be fully warmed up

Instantly should give you a sense of how warm each domain is, too. Is it advancing the %?

Can anyone recommend the best AI model for writing sales emails? I draft around 50 emails daily and need a reliable tool to help streamline the process. Any suggestions for specific LLMs or platforms would be appreciated!

Should not take more than 14 -18 days to warm up. We use smartlead for the same painpoint that you mentioned for us internally and also for our GTM clients at www.pixelodigital.com

I used lemwarm recently and it took me 3 weeks to warm up. Granted, it will depend on the volume you'll be sending.

Ahmed S. 14-18 days sounds too optimistic. May I know what the industry was?

The number was for Fintech we we have tried recently. Also, I agree with you on the optimistic part but THIS is what we have been seeing in the recent period. Would love to understand what is the industry that you are targeting and see if we can help.

Instantly suggests 10-14 days. It will also leave your domains at risk of being auto-blocked by Google through one of their 'sweeps' due to the way they have built their infrastructure no matter your own behaviour and despite following their best practice, then they won't tell you about it when you have been blocked and when you realise what's happened, they won't refund you. Spot the disgruntled customer 👍
