we are a billing company and need to send large volumes of mail to various people from various companies.
We have recently started to use smtp.com to send our mail, but this is going very slow 3 emails per minute.
To improve delivery, here is your SPF information to add to your DNS settings:
SPF record: "v=spf1 include:_spf.smtp.com ?all"
If any questions or concerns arise, please do not hesitate to contact us.
will adding this record affect our current mail set up?
