One of the biggest differentiation OnVoard have over other email marketing platforms is the flexibility we provide for SMTP (Simple Mail Transfer Protocol). We've are using Amazon SES for default sending.

In the past our default choice of delivering emails is via Postmark. But since they got bought over by ActiveCampaign, they've heavily increase their price and we don't use or recommend them anymore.

We now deliver emails via Amazon SES by default.

 

Updated: SPF and DMARC Requirements from April 2025

Starting April 2025, OnVoard require new sending domains to setup both SPF and DMARC before they can be eligible for sending. All email senders should refer to guide below to ensure they've met the new requirements so that your emails gets delivered to inbox.

 

What is a SMTP Profile?

SMTP profile determines the SMTP configurations used for delivering and via which domain. OnVoard doesn't do the actual delivery of emails. Instead, we're integrated with SMTP providers like Amazon SES, Sendgrid and Postmark which will do the job for email delivery. By default, emails will be delivered via OnVoard's Amazon SES account. There are other options you can configure to determine how you want your emails to be delivered. For example, via your own domain or even using your own SMTP provider account.


How to use SMTP Profile?

See link below on how you can use created SMTP profile.

 

Sending Options

In general, there are 3 kinds of sending options you can configure for SMTP profile.

 

1) Use onvoard-mail.com (Default)

This is the default option provided for all accounts. Emails will be delivered via onvoard-mail.com domain using OnVoard's Amazon SES account. For better control over deliverability, we recommend most users to choose option 2 and use your own domain for sending. Emails sent from your own domain will not have "via onvoard-mail.com" message.

Sending from your own domain

This is what we recommend for most users. Delivering via your own domain ensures that you can build up email reputation for your own domain. This is better for your business in the long run since you have better control over deliverability.

Your emails will be delivered using OnVoard's Amazon SES account under your own domain.

 

3) Use your own SMTP provider account (For advanced users)

For advanced users, you can even configure to use your own SMTP provider account for sending. Below are the benefits for doing so:

  • You will gain full control over deliverability. For example, you can setup dedicated IP in your SMTP provider account for sending.

  • Save usage charges. OnVoard will charge your email transit usage instead of email sends usage when you use your own SMTP for sending.

  • More in-depth email stats. You can login directly to your SMTP provider account to view raw email stats.

Keep in mind that we only recommend this for advanced users who knows what they are doing. For more, you can see the following guides for setting up with own SMTP.
