We have our site domain and email registered with 1and1.
However our site is hosted separately with a dedicated host. Magento 2.2.2.
We utilise the Newsletter Feature for customers who subscribe and receive an email to confirm their subscription upon which they receive a code in a second email
Like many store owners who run newsletter subscription box, many emails are entered by robots without permission of email address owner. Therefore, any automated emails triggered received by those spam email addresses may result in the owner themselves reporting our email address.
I have heard recently that actually we should ensure that our ip address of our store is separate from our emails to ensure our site isn't penalised by search engines. I believe we meet this criteria since our store is hosted separately from where emails are sent.
However, i still worry for customers who receive transactional emails and the deliverability. Is there something that can be done to send emails via a method that reduces us being marked as spam for newsletter related emails that are sent? I've read about SMTP but am not sure how this works. Also I checked magento https://docs.magento.com/m2/ce/user_guide/system/email-communications.html who have recently said to avoid sendmail.
I am new to this. please kindly advise.
Best regards,
