Email marketing that stays yours.
SendAnchor is a product of ByteVault Enterprise, built for teams that want to own their sending infrastructure. Connect your own SMTP, keep your list, and pay once instead of paying per email.
Own the infrastructure
Your SMTP account sends the mail. Your domain carries the reputation. SendAnchor is the workspace around it, not a relay that sits between you and your list.
Pay once, not per email
Lifetime plans remove the per-email tax that punishes a growing list. You pay your SMTP provider for sending and keep the rest of the stack predictable.
Built for agencies
White-label client workspaces, per-client SMTP, roles, and reporting. Run every client from one login without another monthly platform bill.
Why we built SendAnchor.
Most email tools charge by contact or by send, then keep your list inside their platform. We wanted the opposite: a tool that works with the infrastructure you already own.
The problem
Per-email pricing makes a healthy list expensive. Per-contact pricing makes growth a penalty. Agencies end up paying twice: once for the platform and again for every client workspace. The list becomes a hostage, not an asset.
Our approach
SendAnchor connects to the SMTP account you already have. You keep the sending relationship, the domain reputation, and the contact data. The product gives you campaigns, automation, forms, tracking, and client workspaces without a per-email markup.
What we believe.
Four rules shape the product and the company behind it.
You should be able to leave with your list and your sending setup intact.
One price, clear limits, and no surprise bill when the list grows.
A small product team, direct support, and software that does the boring parts well.
No selling contact data. No advertising cookies. No mystery subprocessors.
Built by the people who answer the email.
SendAnchor is run by a small team. The people who build the product also read the support inbox, which keeps the feedback loop short and the roadmap honest. If something is broken, you are not routed to a call center or a chatbot.
