Hi friends! , Just a good one. A Hubspot client using Marketing Pro wants to improve email security by update SPF, DMARC, DKIM, Global IT answer it´s not possible to config a SPF for hubspot and or any other third party. GLOBAL IT solution is to use a SMTP relay with hubpot: | 1. Use our smtp relay to send emails ( below points) To passthrough the smtp relay, some condition must be met such as: a. The sender Server IP should be provided to us, so that we can authorize it on the relay server to send the emails b. The Sender Server IP should not be a range of IPs, but a dedicated IP. c. The Sender Server IP must not be an open smtp relay. | My question to all of you: Can you do it just with a dedicated IP ( ADD-ON) .? or In order to do this you need to buy and config SMTP Transactional email . AND that means will work just for transactional emails? ( ex. Marketing emails are with the unsubscribe and modify footer options in opposite of transactionals emails and if you use GDPR this will be a issue) Thanks a lot! JP 😉 ---

Hi @jpsanchez I’ll begin by discussing the Transactional Email aspect - Transactional emails are currently defined as `commerce receipts`, `account updates`, and `system messages` with full engagement tracking across all of your emails. You can find a great level of detail on this here: > **[Inform Customers with Transactional Email Software | HubSpot](https://www.hubspot.com/products/marketing/transactional-email)** > > With HubSpot’s transactional email add-on, you can send personalized emails to customers including automated receipts, account updates, and system messages. These would be separate to the normal emails being sent via the Marketing Email tool and so, if these are the types of emails you’re wanting to continue sending, this is not the add-on that will work for you. If we jump over to the Dedicated IP Add-on, this gives you full control over your email sending and is usually considered if you want to do the following: - _Maintain permission-based, engaged lists of contacts._ - _Need complete control over your sending reputation._ - _Send more than 100,000 messages every month._ - _Send email with your domain, no setup required._ In this case however, you have specific points that fall outside of the usual reasons for requesting this. If we delve into the points though, we can see that the Dedicated IP will provide the functionality you’re looking for: ```auto a. The sender Server IP should be provided to us, so that we can authorize it on the relay server to send the emails - Yes. b. The Sender Server IP should not be a range of IPs, but a dedicated IP. - Yes. c. The Sender Server IP must not be an open smtp relay. - Yes. ``` If this is something you’re interested in, i’d recommend getting in-touch with our team or taking a look at some more information that can be found here: > **[Deliver Emails with a Dedicated IP Address | HubSpot](https://www.hubspot.com/products/marketing/dedicated-ip)** > > Take total ownership of your email deliverability and brand reputation with a dedicated IP address. Monitor your IP address and keep a high sender score. I hope this helps! ---
