I'm seeking advice on email deliverability issues I'm experiencing with my two domains, which I've referred to as company.com and brand.com for this discussion. My primary setup involves using Google Workspace with company.com as the main domain and brand.com as an alias, allowing me to send emails from both. I utilize SendGrid for sending transactional emails and our monthly newsletter, which reaches over 70,000 recipients. I often compose emails manually through Gmail or my CRM using brand.com.
Despite using various tools like Lemlist, Mailchimp, and now SendGrid/Salesflare, I've faced challenges with emails landing in spam. Previously, manual outreach to hundreds of contacts in a day likely impacted my domain's reputation. At this point, my main email activity is sending the monthly newsletter and transactional emails as user volume increases.
I'm wondering if it's a bad idea to use brand.com consistently for my communications. I've come across recommendations about email warm-up tools and the use of different domains, but I'm feeling a bit overwhelmed. Would using a subdomain (like newsletter.brand.com or app.brand.com) to distinguish my newsletter from my app-related emails be beneficial? If so, do I need to warm up these subdomains before using them?
Alternatively, should I consider a completely different domain, such as brandapp.com, for my newsletter? If I go this route, would testing it with a warm-up tool be necessary? I'd rather not set it up in Google Workspace to avoid additional costs. Also, I've been using both domains for over two years and have already established SPF, DKIM, and DMARC records.

It's definitely a good strategy to use a subdomain for different types of emails. By launching your newsletter from a subdomain like newsletter.brand.com, you can separate that email activity from your app's transactional emails and your personal outreach. Just ensure you have all the proper SPF, DKIM, and DMARC records set up. The term "enablements" refers to the configurations that allow those records to work correctly, like making sure your DNS settings are accurate.
If you want to keep your main domain reputation intact, using subdomains is a smart move. They do need to be 'warmed up' a bit before you begin sending large volumes of emails from them. This process helps build a positive reputation before you start blasting out your newsletter. As for using a different domain entirely, that's an option too, just remember that you would want to warm that up as well.
