# Sender addresses & names
> Confirm the mailboxes you send from, keep a reusable list of From names, and set a workspace default sender.
Every marketing email carries a From name and a From address. In Senderz both are managed lists, so your team picks from approved values instead of typing something different every time.
You manage them in **Settings → Domains & senders**, under the domains table. There are three cards: **Sender addresses**, **Default sender** and **Sender names**.
These are email settings. They are not the same thing as an SMS Sender name,
which is a separate branded From name for text messages and lives in
**Settings → SMS Sender names**. See
[SMS sender IDs](/en/deliverability/sender-ids).
## Sender addresses
A sender address is a real mailbox on one of your verified domains, for example `hello@example.com`. It is what recipients see, and it is where their replies and any bounces go.
**A verified domain is not enough on its own.** Each address has to confirm itself before it can send.
In the **Sender addresses** card, type the part before the @ and pick the
domain. Only verified domains appear in the list. If none do, verify a
domain first. See [Domains & authentication](/en/deliverability/domains).
Senderz emails that mailbox a confirmation link. Someone who can read the
inbox opens it, and the address flips to **Verified**. The confirmation
page tells you which address was confirmed.
The address now appears in the sender picker in the campaign builder and
in automation email steps.
The mailbox has to confirm because replies and bounces have to land
somewhere real. Nobody at Senderz reviews or approves the address. Opening
the link is the whole approval.
### Statuses
| Status | What it means | What to do |
| --------------------- | ------------------------------------------------------------------- | --------------------------------------------------- |
| Verified | Confirmed. It can send. | Nothing. |
| Awaiting verification | The confirmation email was sent and nobody has opened the link yet. | Open the link, or choose **Resend**. |
| Failed | The confirmation email could not be delivered. | Check the mailbox actually exists, then **Resend**. |
The list refreshes on its own while any address is awaiting verification, so it turns green shortly after someone opens the link.
### Resending
Choose **Resend** on the row. There is a one minute wait between sends, so a fast second click tells you a verification email was just sent and to try again in a minute.
Confirmation links are valid for **48 hours**. An expired link cannot be reused. Resend to get a fresh one. Resending also replaces the previous link, so only the newest email works.
### Limits and removal
You can hold up to **100 sender addresses** per workspace. Choose **Remove sender address** to delete one.
Removing a domain removes every sender address on it.
If you send from an address that has not been confirmed, the send is
refused with **This sender address has not been verified yet. Confirm it
from the verification email before sending.** The campaign review step
catches this before you schedule, and the error links straight back to this
screen.
## Sender names
A sender name is the From name recipients read next to your address, for example `Tamar from Senderz`. The list is workspace wide and is not tied to a domain, so any name can pair with any address.
Use the **Sender names** card to add one, and the menu on each row to **Edit**, **Duplicate** or **Delete**. Duplicating creates a copy with `(copy)` appended, which is handy when you want a small variation. Each row shows how many emails have gone out under that name and when it was last used.
You can hold up to **50 sender names** per workspace.
### Name validation
Senderz checks a name as you type and shows the result under the field.
* The characters `<`, `>`, `@`, `"`, `[`, `]` and backslash. They break the
From header outright.
* Line breaks and other control characters.
* Names over 100 characters.
* Punctuation like `.` `,` `:` `;` `(` `)`, which some inboxes render
oddly because it has to be quoted.
* Repeated punctuation such as `!!!` or `***`, which can trigger spam
filters.
* Emoji, which hurt deliverability and render inconsistently across
inboxes.
* Anything that looks like a link or a domain name, which can be read as
spoofing.
* Names over 60 characters, because some inboxes shorten them.
A recognisable human name plus your brand tends to perform best, for example
`Tamar from Example`. Keep it stable. Recipients filter and search on the
From name, so changing it often costs you engagement.
## Default sender
The **Default sender** card holds one name and one address for the whole workspace.
It does two things.
New campaigns and new automation email steps start with these values
already filled in, so nobody has to remember them.
If a campaign or an automation email step has no sender of its own when
it sends, the default is used. The name and the address fall back
independently.
The address must already be a verified sender address on a verified domain. If you pick one that is no longer verified, the card says so and the save is refused.
### Apply to all messages
Setting the default only affects new work and send-time gaps. To stamp it onto what already exists, choose **Apply to all messages**.
Before it runs you get an exact count, for example that the sender email will be applied to 4 campaigns and 2 automations. Confirm to apply.
It rewrites campaigns that are draft, scheduled or paused, and email steps
in automations that are draft, active or paused. **Campaigns that have
already sent are never changed.** The action is recorded in your workspace
audit log.
## Errors you might see
| What you see | What it means |
| ------------------------------------------------- | ------------------------------------------------------------------------------------------- |
| This sender address has not been verified yet | The From address exists but nobody opened its confirmation email. Resend and open the link. |
| From address must use a verified sending domain | The domain behind the address is not verified, or lost its DNS records. |
| Verify this domain before adding sender addresses | You tried to add an address on a domain that has not verified yet. |
| This sender address already exists | That address is already in the list, possibly awaiting verification. |
| This verification link has expired | The link was older than 48 hours. Resend to get a new one. |
| A verification email was just sent | The one minute resend wait has not passed. |
Send-time failures also show up in the campaign review checklist before you schedule, and on a failed campaign as a named reason rather than a generic error.
## Who can do what
| Action | Who |
| ------------------------------------------------------ | -------------------- |
| Add, remove or resend a sender address | Owner, admin |
| Add, edit, duplicate or delete a sender name | Owner, admin |
| Set the default sender and apply it to all messages | Owner, admin |
| View sender addresses and names, pick one when sending | Any workspace member |
Confirming a sender address does not need a Senderz account at all. Anyone who can read that mailbox can open the link.
