2b:T451,<@U0680J3FQMS> I watched the webinar _“Maximize Your Email Deliverability,”_ where I learned about ethical email list building. I’m currently on the Scale Plan and have one publication: — a weekly educational blog/newsletter — that is growing organically as people sign up. I’m now creating a second publication focused on email outreach for updates about my medical practice. The marketing team from one of the medical device companies we’re partnering with provided a CRM list of 500 segmented contacts with email addresses. This is *not* a purchased list — but the individuals on it did not give their email addresses to me directly. These are other medical practices and clinicians (not patients). I was thinking of sending small batch emails to different segments in these contacts announcing our new medical offerings. However, I’m concerned: since these recipients haven’t explicitly opted in, will this first email trigger spam filters — even if I include clear messaging on how to unsubscribe? 2c:T4d4,Great question <@U08UZ8N4M8R> I’m also in a similar dilemma. <@U047A59BMA5> you helped clarify earlier on using as a custom subdomain for my Beehiiv newsletter on my private practice site: . Now, we have Microsoft email going out with @noesisclinic.com so I guess the is also already linked to the private practice emails. Would linking Beehiiv send from emails to potentially mess up my current private practice business emails? In that case, can I have my cake and eat it too, in that: i get a custom Beehiiv subdomain on but have the newsletter emails still being sent out from Beehiiv? Thank you for walking me through it. I’m wanting to, through the blog
