Here is the strategy you may consider in creating a secondary domain to scale up your cold outreach, get more replies, and more revenue. Watch the video about scaling your cold email campaigns by clicking the link here.
Buy domains that are similar to your main domain.
We’ve run an analysis recently on 32M cold emails and have seen worse performance (reply rate) with domain extensions such as biz, online etc. You may check this list to know the domains with the worst reputation.
Avoid hyphens and numbers, use letters only.
.com and country domain extensions (.de, .be etc.) work best. We’ve had success with domains like .agency .tech too, but if possible, buy .com domains. These are more expensive but considering the volume that a single domain can send (100+ emails a day) for months the additional $8 is well worth it.
We recommend 2-3 email accounts/inboxes per secondary sending domain.
If your business is called Shrimp.com, then buy domains on the following list.
Getshrimp.com
Tryshrimp.com
TastyShrimpApp.com
