Technolutions is capable of sending DMARC compliant email because they support custom SPF and DKIM configurations that achieve DMARC alignment. Technolutions is an Education Platform and is often used by Marketing and Product teams.
The link just below is a resource on how to configure this source to send DKIM-aligned email on your behalf. You will complete this configuration by (1) following the source's instructions and (2) adding the required entries into your DNS. https://knowledge.technolutions.com/hc/en-us/articles/360032624372
Though Technolutions suggests they support custom SPF configurations, they recommend leading with DKIM initially. DMARC only requires SPF or DKIM, not both.
