Glossary

In short

Every term SendPath uses, in plain language. Underlined words in the docs link here.

A/B test (variant): Two to five versions of the same email step, split between contacts, to see which one gets more replies. Read more
App password: A separate password that Gmail or Yahoo creates for one app, so you never share your real password. Read more
Bounce: An email that couldn't be delivered, usually because the address doesn't exist. Too many hurt your domain. Read more
Cold email: A first email to someone who doesn't know you yet, sent one to one from a real mailbox. Read more
Credits (SendPath AI): What SendPath AI's writing uses. Each job uses what it actually costs; sending never uses credits. Read more
Daily cap: The most emails one mailbox sends in a day, campaigns and warm-up together. 50 unless you change it. Read more
DKIM: A signature on every email that proves it wasn't changed on the way. Your email provider gives you the record. Read more
DMARC: A DNS record that tells inboxes what to do with mail that fails SPF and DKIM. Gmail and Yahoo expect one. Read more
DNS: Your domain's public settings, kept where you bought or manage the domain (Cloudflare, GoDaddy, Namecheap...). Read more
Domain: The part of an email address after the @, like acme.com. Its reputation is shared by every mailbox on it.
Follow-up: A later step of a sequence, sent only to contacts who haven't replied yet. Read more
IMAP: How SendPath reads a mailbox, to find replies and bounces. Read more
Inbox placement: The share of emails that land in the inbox (a Promotions tab counts) rather than spam. Read more
MCP: The standard way AI apps like Claude and ChatGPT connect to other tools. SendPath's MCP connection can only read. Read more
MX record: The DNS record that says which server receives your domain's mail. Without it, replies bounce. Read more
One-click unsubscribe: The Unsubscribe button Gmail and other mail apps show next to the sender. SendPath adds it to every email. Read more
Open and link tracking: Counting opens with an invisible image and clicks with a redirect. Off by default: both can hurt inbox placement. Read more
Pre-send gate: The checks every campaign and every email must pass before it's sent. Nothing can skip them. Read more
Ramp: Warm-up's slow start: 3 emails on day 1, then a few more each day, up to the mailbox's warm-up limit. Read more
Reply-to: An address that replies go to instead of the sender. Leave it empty so SendPath can read the replies. Read more
Seed mailbox: One of SendPath's own mailboxes that receives warm-up emails, opens them, rescues them from spam and replies. Read more
Sender (mailbox): A mailbox you connected to send from. You own it; SendPath sends through it and reads its replies. Read more
Sender reputation: How much Gmail and Outlook trust mail from your domain and mailbox, built from how people react to it. Read more
Sequence: A campaign's emails in order: the first email and its follow-ups, with a wait before each. Read more
SMTP: How a mailbox sends email. SendPath sends through your mailbox's SMTP server. Read more
Spam complaint: When a recipient clicks Report spam. A few of these can send your next emails to spam.
SPF: A DNS record that lists who may send email for your domain. Without it, most mail is rejected or lands in spam. Read more
Spintax: {{RANDOM | Hi | Hello}}: each contact gets one of the options, so your emails don't all read the same. Read more
Suppression: An address that is never emailed again from your workspace: unsubscribes, bounces and ones you add. Read more
Test email: The campaign's emails sent to you once. Required before a campaign starts, and again after the emails change. Read more
Variable: A placeholder like {{first_name}} that is filled in from the contact's row in your list. Read more
Verification: Checking each address before it's emailed: each one comes back valid or invalid, and only valid ones are sent to. Read more
Verification credit: Checks one address once your plan's verifications for the month are used. Bought in any amount; never expires. Read more
Warm-up: A mailbox sending a few ordinary emails a day to seed mailboxes, so inboxes learn to trust it. Read more
Workspace: One company's mailboxes, lists, campaigns and team, with its own plan. Agencies use one per client. Read more
