Constant Contact sends the campaigns. Your domain still has to earn the inbox.
Constant Contact looks after the reputation of its shared sending infrastructure, but once you self-authenticate, the domain’s reputation is yours, and there is no tool in the account that warms it. Keep your campaigns exactly where they are. Add your brand domain here and we build its reputation while Constant Contact keeps sending.
Keep sending from Constant Contact. Warm the domain here.
Self-authenticate your domain in Constant Contact
Until you do, Constant Contact rewrites your From address to a shared ccsend.com address and your reputation is pooled with other customers. The CNAME option is the one Constant Contact recommends for most accounts; the TXT option suits several accounts sending from one domain. Either way you also publish a DMARC record.
Know what Constant Contact handles, and what it does not
Mail goes out on Constant Contact’s shared infrastructure, and the vendor handles its IP reputation. Self-authenticating makes the domain’s reputation yours, and Constant Contact offers no ramp or schedule for building it.
Add your brand domain to Inbox Boost
Use the domain in your From address, such as yourbrand.com. The records you added to self-authenticate stay with Constant Contact. We set up what the domain needs and build its sender reputation for you. Nothing to connect to Constant Contact: no API key, no app, no change to your account.
Keep every campaign running in Constant Contact
Newsletters, event invitations, announcements: all of it stays in Constant Contact. Mailbox providers score the domain in your From address, so the reputation built here counts for every Constant Contact send from yourbrand.com.
Check where Constant Contact mail lands
Inbox placement tests show whether your campaigns reach Primary, Promotions or Spam across the major mailbox providers, and blacklist monitoring keeps watching the domain once it is warm.
- Nothing to connect: no Constant Contact API key, app or integration
- Nothing to change: lists, templates and schedules stay exactly as they are
- Built for shared IPs: the IPs are shared, so the domain is the reputation that is yours
- Watched after warmup: blacklist and authentication monitoring on your brand domain
