your batch cooking recipes

Hi Laura, I came across your batch cooking recipes for people short on time and they're some of the most practical nutrition content out there.

How are you bringing in new patients these days?

your 7 a.m. classes

Hi, I noticed that at Atlas you fill up your 7 a.m. classes and people keep coming back, which is the hard part for a neighborhood gym.

Are you looking for members for the midday slots?

your approach with athletes

Hi Marc, I was struck by how you handle nutrition plans for amateur athletes without pushing supplements on them, which is rare in your field.

Would you like to reach more clubs in your area?

How many first appointments would you like to book each month?

Frequently asked questions

Cold email doesn't work anymore, right?

It does work, but only when the email lands in the inbox and says something relevant to the person receiving it. What has stopped working is blasting the same message from unprepared accounts. That's exactly what we solve: careful delivery and messages that add value.

Will my emails end up in spam?

We warm up your accounts on a private network, send mimicking human behavior (pace, real opens and replies) and monitor the health of your mailboxes and domains. If anything drifts, you'll see it on the dashboard before it affects your campaigns.

I don't know how to write emails. Is that a problem?

No. Give Email AI your instructions (your business, your offer and who you're targeting) and it writes the whole sequence for you. You also have proven templates you only need to adapt.

Is it very technical to set up?

No. If you don't want the hassle, we buy and set up your accounts and domains in four clicks: we take care of authentication (DNS, SPF, DKIM, DMARC), warm-up and connecting them to your campaign.

Do you charge by sending volume?

No. Unlimited email accounts and lead storage: you don't pay more to send more.

Is cold email legal?

Yes, under the right conditions. We only work with public data from professional profiles, within the framework of the GDPR and the CAN-SPAM Act, and we include an unsubscribe option in every send.

Start winning customers with emails that actually arrive.
