Total Send offers high volume customers the option of sending from a dedicated/private IP address. A big advantage of a dedicated IP address is that you won't be affected by the mistakes of others (e.g., too many spam complaints) that can get them blocked. With a shared IP address, one bad sender can get everyone sharing the IP address blocked by the ISPs. This option is available to smaller senders as well for a fee.
If you are planning to send to more than 10,000 recipients at a time, it is important to ramp up your email sending in order to build the reputation of your IP address. The problem is if you were to send out a large number of emails immediately upon getting a new dedicated IP address, the ISPs are much more likely to defer or block your emails.
Once you have ramped up successfully, you can send much higher email volume and get it through the ISP's filters successfully. Recommended Schedule (campaigns should be broken up into smaller batches and sent every 4 to 6 hours to evenly spread the volume throughout each day):
- Send to 5,000 recipients on days 1, 2 and 3
- Send to 10,000 recipients on days 4, 5 & 6
- Send to 20,000 recipients on days 7, 8 & 9
- Send to 40,000 recipients on days 10, 11 & 12
- Send to 80,000 recipients on days 13, 14 & 15
- Send to 160,000 recipients on days 16 +
- 20,000 (10,000 twice a day, 6 hours apart) day 1 & 2
- 40,000 (10,000 four times a day, 6 hours apart) day 3 & 4
- 80,000 (20,000 four times a day, 6 hours apart) day 5 & 6
- 160,000 (40,000 four times a day, 6 hours apart) day 7 & 8
- 300,000 (75,000 four times a day, 6 hours apart) day 9 & 10
