# Use SendGrid, Postmark, Resend, Mailgun or SMTP instead of SES

Source: https://help.meisa.io/articles/connect-another-email-provider

Meisa works with the email provider you already use. Open **Email setup**, click **Connect a provider**, pick **SendGrid**, **Postmark**, **Resend**, **Mailgun**, **Brevo**, **SparkPost**, **Mailjet** or **Custom SMTP**, paste the API key (or SMTP login) and click **Add provider**. You pay the provider directly, at their price.

## Connect a provider

1. Click **Email setup** in the sidebar.
2. Click **Connect a provider** (or **Add a provider** if you already have one).
3. Choose your provider from the list.

4. **Name (optional)**: a name you will recognise.
5. Fill in the fields for your provider (see below).
6. Click **Add provider**. Meisa checks the key right away. If the provider rejects it, you see "... did not accept these details. Check them and save again."

## What each provider needs

| Provider | Fields in Meisa | Where to get them |
|---|---|---|
| **SendGrid** | **API key** (starts with `SG.`), **Region** (Global or EU), **Dedicated IP pool** (optional) | SendGrid, **Settings**, **API Keys**. Give it Mail Send, plus Domain Authentication if you verify your domain in Meisa, plus webhook settings access for delivery tracking. |
| **Mailgun** | **API key**, **Sending domain** (for example `mg.yourdomain.com`), **Region** (US or EU) | Mailgun, **Account Settings**, **API Security**. Use your private API key. The region must match where the domain was added in Mailgun. |
| **Postmark** | **Server API token**, **Message stream** (optional) | Your Postmark server, **API Tokens** tab. Use a Broadcast stream for newsletters and marketing: Postmark does not allow them on its transactional stream. |
| **Resend** | **API key** (starts with `re_`) | Resend, **API Keys**. Sending access is enough. |
| **Brevo** | **API key** (starts with `xkeysib-`) | Brevo, **SMTP and API**, **API Keys**. |
| **SparkPost** | **API key**, **Region** (US or EU) | SparkPost API keys. The key needs the Transmissions permission. |
| **Mailjet** | **API key** and **Secret key** | Mailjet account API key settings. |
| **Custom SMTP** | **SMTP host**, **Port** (usually 587), **Username**, **Password**, **Use TLS encryption** | Your SMTP service's connection settings. |

## Verify your domain

Domain checks inside Meisa depend on the provider:

- **SendGrid and Mailgun**: add your domain under **Verify your domain** in Meisa, exactly as for SES. Meisa gets the DNS records from your provider and checks them for you. See [Verify your sending domain](/articles/verify-your-sending-domain).
- **Postmark, Resend, Brevo, SparkPost, Mailjet and Custom SMTP**: verify your domain in the provider's own dashboard first, using the DKIM and SPF records they give you. Then add the domain and a sender in Meisa. If your sender stays **Not verified**, email hi@meisa.io with your domain and we will sort it out.

## Turn on delivery tracking

So bounces and spam complaints come back to Meisa:

1. Finish the setup steps, then in **Email setup** click the **More actions** menu (three dots) on the provider.
2. Click **Set up delivery tracking**.
3. **SendGrid**: confirm with **Set up tracking**. Meisa adds a signed event webhook in your SendGrid account.
4. **Mailgun**: click **Set up tracking**. Meisa creates the delivery, bounce and complaint webhooks and fetches your webhook signing key. If that fetch fails, paste the key into **Webhook signing key (optional)**. Find it in Mailgun under **Account Settings**, **API Security**, **HTTP webhook signing key**.

Meisa tracks opens and clicks itself for every provider, so your provider's own dashboard may show zero opens and clicks. That is expected.

## Using more than one provider

You can connect several providers, for example SES for newsletters and Postmark for transactional email.

- The **Default** provider is used unless a sender says otherwise. Change it with **Set as default** in the provider's **More actions** menu.
- Each sender has a **Sends through** setting that picks its provider.
- **Disable** stops sending through a provider without deleting it.

## Troubleshooting

- **SendGrid key works but tracking fails**: the key lacks webhook settings access. Create a key with those permissions and update it with **Edit**.
- **Mailgun sends fail**: check **Sending domain** is the domain verified in Mailgun (not your main website domain) and that **Region** matches it.
- **SMTP test fails**: use port 587 with **Use TLS encryption** ticked. Port 465 (direct SSL) is not supported in the form, and port 25 is often blocked. Check the host, username and password with your SMTP service.
- **Postmark rejects marketing emails**: set **Message stream** to your Broadcast stream ID.
