Hi @RSiddula,
Could you confirm that you have connected your email sending domain and set up email authentification (SPF, DMARC)? Both are considered best practice and should help with your email deliverability and would be the first steps towards better deliverability.
In general, similar to SEO, you want to try to pass on as many positive signals about your content as possible. With that in mind, here is a list of things that I’d recommend reviewing:
Connect your email sending domain
Use a DMARC policy with HubSpot
Only email contacts who for whom you have a legal basis to communicate
Validate emails before sending to avoid hard bounces at all costs (e.g. Neverbounce, Zerobounce)
Remove unengaged contacts from list regularly for higher engagement rates
Avoid as many spam trigger words as possible
Test the spammyness of your email
If you have already taken some of these steps or more context to share, let me know.
Best regards!
PS. You do not need to submit your posts twice. There are plenty of experts who will see your post if you submit it once.
