# Email sending and sender

> Who your restock emails come from, which mail server sends them, and how to check what went out.

Three places decide what a shopper sees in their inbox and whether it arrived:

| What | Where |
| - | - |
| Sender name, from address and reply-to | **Appearance → Notifications → Email**, the **Email** section |
| The mail server | **Settings → Email sending** |
| What was sent, and what failed | **Settings → Communication logs** |

## Sender name and reply-to

Open **Appearance → Notifications**, choose **Email**, and expand the **Email** section. These
apply to all four notification steps, not just the one you are editing.

| Field | Default |
| - | - |
| **Sender name** | Your store name. Type another name to send as that instead. |
| **From email address** | The Notifylyst default address. Your own address needs your own SMTP server (below). |
| **Reply-To email address** | Your store admin email — where shopper replies go. |

The store details card on the **Settings** page (time zone, currency, owner email) is read-only
here; change those with **Edit in Shopify settings**. Exports and reports use your store's time
zone.

## Email sending — Notifylyst or your own server

**Settings → Email sending** has two choices:

* **Notifylyst mail servers** (*Recommended*, the default) — no setup, no DNS records, no
  credentials. The right choice for most stores.
* **Your own SMTP server** — send through your own mail provider. Reasons to bother: your own
  domain's reputation, compliance rules that require mail to leave your infrastructure, or you
  already run a transactional mail provider.

For your own server, fill in:

| Field | Notes |
| - | - |
| **SMTP host** | Must be a public internet address, for example `smtp.example.com`. |
| **Port and encryption** | Port **587** by default; encryption **None** (default), **SSL** or **TLS**. Usually 587 with TLS, or 465 with SSL. |
| **Username** / **Password** | From your mail provider — for SendGrid the username is `apikey`. The password is never shown again after saving. |
| **Send from** | The address shoppers see. Use one your SMTP account is allowed to send from. |

![Settings → Email sending with Your own SMTP server selected and the host, port, encryption, username, password and send-from fields; the values are blurred.](https://mintcdn.com/codebeans-cb-notifylyst/helB_Y1ZQRw5r3Uo/images/app-11-smtp.png?fit=max\&auto=format\&n=helB_Y1ZQRw5r3Uo\&q=85\&s=7ad6143ea881be08fd93c265ac27c81c)

Using your own server depends on your plan (**Custom SMTP**). Messages you may see:

| Message | Fix |
| - | - |
| **SMTP host must be a public internet address.** | Use your provider's public host name, not an internal one. |
| **SMTP port must be a number between 1 and 65535 (usually 587 or 465).** | Correct the port. |
| **Sender email must be a valid email address.** | Correct **Send from**. |
| **Enter an SMTP host before enabling custom SMTP.** | Fill in the host first. |

Then send yourself a test from **Appearance → Notifications** and check
**Communication logs**.

## Communication logs

**Settings → Communication logs** lists every message Notifylyst sent for your store — restock
alerts, summary reports, sign-up alerts and exports. Filter by what it was, channel, status
(**Sent**, **Failed**, **Pending**) and date, or search. Failed rows show the reason.

If nothing was sent you see **Nothing was sent in this period with these filters.**

![Settings → Communication logs with filters for type, channel, status and date above the list of sent messages.](https://mintcdn.com/codebeans-cb-notifylyst/helB_Y1ZQRw5r3Uo/images/app-12-comm-logs.png?fit=max\&auto=format\&n=helB_Y1ZQRw5r3Uo\&q=85\&s=c3dca3680cd9e2f8585000db0c0bcc5c)
