The answers present a wide range of opinions and data points. While some users have had success with dedicated IPs at volumes as low as a few thousand emails per day or around 20,000 per month, the general consensus leans toward higher volumes being necessary to maintain a good sender reputation and justify the cost and effort. Most sources suggest a minimum of 50,000 emails per month, with several recommending 50,000 per week or even 100,000 per week. Furthermore, maintaining a consistent sending volume and proper IP warm-up are crucial factors. It's also highlighted that a good reputation, rather than solely volume, plays a key role. Additionally, if deliverability issues arise specifically with Gmail, the problem is less likely to be directly related to the IP address.

The general consensus is that a dedicated IP address is best suited for senders with high email volumes. While some have used dedicated IPs with volumes as low as a few thousand per day, most recommendations point to needing at least 50,000 emails per month to justify a dedicated IP. Some sources suggest 50,000 emails per week, or even up to 100,000 emails per week, are needed to maintain a good reputation. Using a shared IP is recommended for lower volumes. Negative email metrics do not scale down with overall volume.

Email marketer from Email Geeks uses the rule of thumb of around 100k emails/week to maintain a dedicated IP because it's hard for a sender to maintain a good reputation with mailbox providers with lower volume. They recommend staying on a shared IP until the volume increases unless there are very bad impacts. Also they suggest asking to be moved to a different shared pool if there are blocklists. They state that Sender Score can provide directional guidance, but is not actually used by any provider to filter mail.

The responses indicate varying perspectives on the minimum send volume for a dedicated IP. Some experts have successfully used dedicated IPs with as little as 20,000 emails per day, while others recommend a minimum of 50,000 emails per month, with stronger recommendations suggesting 100,000 emails per week. Volume isn't the only factor, and maintaining a good sender reputation is vital. Deliverability issues with Gmail are unlikely to be IP-related.
