Send emails that reach your recipient

When you send email from your application via Postal instead of via a mail account and SMTP, you get better deliverability and traceability. Mail accounts are often limited in how much you can send out per month.

Yes. In order to send email that is delivered to the recipient, you need to be able to change the DNS records on your domain. When you order Postal, we will provide you with the DNS records (SPF, DKIM) that you need to add to your domain.

These two are the names of different types of methods that have been developed to combat spam. In short, they involve either signing the messages you send to mark them as genuine, or telling you which servers are allowed to send mail from your domain name.

All email you send is received by a receiving server. Since spam is common, most servers check many things when they receive messages to determine if they are genuine. One of the parameters is the reputation of the sending IP address. If others on the same IP address send questionable mailings that recipients think are spam, yours may be affected too.

With a dedicated IP address, you avoid this and avoid the risk of other people’s mailings affecting your reputation.

Absolutely! When you integrate and send with the Postal API, you can get information about your sent messages back to your application via webhooks. For example, you can:

Get a reply back confirming that the message was queued to be sent.

Get a unique message ID. Using webhooks, you can get information to your application if the message has arrived or bounced.

You can also view information about sent messages in the Postal web interface.

Yes. By integrating with the Postal API, webhooks will return information about your sent messages. You can then find out, among other things, when the message was opened and which links the recipient clicked on.

You can also see this information in the Postal web interface.

It depends on how many messages you send per month and how often you send.

As a rule of thumb, if you send more than 100,000 messages per month, you will benefit from a dedicated IP address.
