Summary
What email marketers say13Marketer opinions
Marketer from Email Geeks advises against using a dedicated IP for 30k/month volume because it leaves no room for error as you don't have enough volume to absorb any mistakes/blips that may influence deliverability.
Email marketer from Automated Dreams Brad Smith states that Dedicated IP addresses give you more control over your sending reputation, but they require consistent volume to maintain a good reputation. Otherwise, shared IPs are better for low volume senders.
Email marketer from SendPulse answers that you need to send frequently and consistently if you use a dedicated IP. The company recommends sending at least 50,000 emails per month to maintain a good sender reputation.
Marketer from Email Geeks says 90k/month is better but still pretty low. Says at 90k you need sufficiently large cohort of properly engaged recipients, solid fresh content plan, no outstanding deliverability issues, and tailored warming plan, then you could pull it off.
Email marketer from Mailjet explains that dedicated IPs are best for senders with high volumes (over 50,000 emails/month) to establish a good sending reputation. Low volume senders may find it difficult to maintain a positive reputation, leading to deliverability issues.
Email marketer from Reddit user u/email_marketing_guy shares that a general guideline is that you would need to send around 50,000 emails a month on a regular basis to justify a dedicated IP. Less than this and you may not build the reputation necessary with the ISPs.
Email marketer from ActiveCampaign responds that dedicated IPs are suitable for senders with consistent sending habits and a volume of at least 50,000 emails per month. This volume helps build and maintain a positive sender reputation.
Email marketer from Email Geeks says that to maintain a private IP one needs at bare bones minimum 100k/month, and ideally more around 200k+ to truly establish reputation at a majority of the MBPs.
Email marketer from Email Vendor Selection answers that the key advantage of a dedicated IP is that a high-volume sender can build up their own reputation. This allows them to send as many emails as they want, without having to worry about other senders negatively affecting their reputation.
Email marketer from GlockApps explains that a dedicated IP address means you don't share the IP reputation with other senders. However, if you are a low volume sender, you may consider using shared IP addresses so you can benefit from a good sending reputation shared by other senders.
Email marketer from StackExchange John Doe responds that there is a risk of using dedicated IPs for low-volume sending. If you do not send enough emails, the reputation can not be built by you, which means others sending spam could ruin your IP reputation and that you will never be able to fix it because your IP will remain a low volume IP.
Email marketer from Email Geeks recommends pushing SF to move the client to a better IP. Suggests checking if the client's emails are going out on one IP or rotating between IPs and trying to be moved to the IP with better results.
Marketer from Email Geeks explains that a low volume sender is likely to struggle on a dedicated IP, but it can be done if they are sending wanted emails and their metrics are good, though they generally recommend against it.
What the experts say3Expert opinions
Expert from Word to the Wise responds that if you're sending less than tens of thousands of emails per month, a dedicated IP address is generally not a good idea. You simply don't have the volume to build a good reputation on your own.
Expert from Email Geeks advises against going to a dedicated IP, as it's too small at that level and too risky. Recommends pushing Salesforce Deliverability to fix the issue or provide options.
Expert from Spam Resource responds that if you are a small sender, you probably won't see a benefit to using a dedicated IP. Because you are the only sender on the IP, any reputation both good and bad will be yours. If you do not have much volume, it will take a long time to create a reputation, and thus you will be in a constant state of IP warm-up.
What the documentation says4Technical articles
Documentation from Microsoft explains that sender reputation is influenced by sending volume and consistency. Low volume senders may not meet the criteria for a good sender reputation with a dedicated IP, leading to potential deliverability problems.
Documentation from Google responds that maintaining a positive IP reputation is crucial for deliverability. Low volume senders may struggle to build and maintain this reputation with a dedicated IP, making shared IPs a better option.
Documentation from Postmark responds that if you're just starting out and sending small amounts of emails (less than 50,000 a month), it's best to start on a shared IP. As your volume increases, you can then look at moving to a dedicated IP.
Documentation from SparkPost explains that using a dedicated IP requires a warm-up period to establish a sending reputation. Low volume senders may not be able to warm up the IP effectively, impacting deliverability.
