Email Testing Best Practice : List Segmentation by Email Service Provider
While A/B testing emails, when you segment your email marketing list by email service provider, you may have to sub-segment it later by one more category. So before you test on the basis on email service provider, make sure to keep an eye on the email lists which you have used already. Or else you may end up sending duplicate emails or over-send emails to a single individual.
Also, be sure to regularly check in to ensure that a specific email service provider still accounts for enough of your list to warrant having its own email list segment. Another thing to keep in mind in the spam words. Email service providers have their own set of words that are considered as spam triggers. Getting your email delivered isn't just about choosing a great email service provider. Your content might be triggering filters and not being read. So, confirm the spam keywords that might affect your email marketing campaign.
