Account Setup

Setting up your SlyReply account takes just a few minutes. Once complete, you can start emailing agents immediately.

Registration

Visit the SlyReply dashboard and click Register
Enter your name, email address, and a secure password
Your email address is automatically added to your list of registered emails — this is how SlyReply identifies you when you send messages to agents

Understanding Registered Emails

Your registered email is your identity in SlyReply. When you send a message to an agent, SlyReply checks the sender address against all registered emails to authenticate you. This means:

No passwords in the email flow — your email address is your credential
Multiple emails supported — add work and personal addresses from your profile page
Unknown senders are ignored — messages from unregistered addresses are silently dropped for security

⚠️ Unknown Senders Are Dropped Silently — No Bounce, No Autoreply

This is the single most important thing to understand if you plan to automate anything with SlyReply (auto-forward rules, scripts, scheduled sends):

An email from an address that is not on your registered-emails list > is silently dropped. The sender gets no reply, no error, and no > bounce message. SlyReply deliberately gives no sign it exists — it > never confirms or denies that an agent address is real.

In practice this means:

Only mail you send yourself reaches your agents. A customer, colleague, or stranger emailing your agent's address directly gets nothing back. SlyReply only ever replies to you.
Auto-forwarding works — but check the sender. When you set up a forwarding rule, the forwarded email's From is usually still the original sender, not you. If your forwarding setup doesn't rewrite the From to one of your registered addresses, the email will be dropped silently. Test your rule with a real email and confirm a reply lands before you rely on it.
No news is not good news. Because failures are silent, "I didn't get a reply" can mean the sender wasn't registered, the email was over a limit, or something else — there is no bounce to tell you which. If an agent goes quiet, check that you sent from a registered address first.

To add another address you send from — a work account, a script's mailbox — add it on your Profile page before you rely on it.

Spoof Protection on Your Account

Because your From address is your credential, SlyReply guards against someone forging it. Every inbound email is checked against the standard email-authentication signals — SPF, DKIM, and DMARC-style domain alignment:

An SPF hard-fail (the sender domain explicitly says that server is not allowed to send for it) is dropped for every account.
On Pro and Power accounts, an email that fails DKIM or whose signing domain doesn't align with the From address is also dropped, so a spoofed message can't impersonate your registered address. An operator-managed allowlist covers legitimate forwarders that don't re-sign mail.
On the Free tier, alignment failures are recorded for review rather than dropped.

You don't configure any of this — it runs on every inbound email automatically. It's worth knowing about if you forward mail through a relay or mailing list that may break DKIM signing: prefer forwarding from a mailbox whose domain you control, or contact support to allowlist a trusted forwarder.
