Deliverability problems – SPF/DKIM parameters

It’s important that you include the SPF/DKIM parameters in your DNS settings. SPF (Sender Policy Framework) is a DNS text entry which provides a list of servers that should be considered allowed to send emails for a specific domain.

The correct SPF would be – “v=spf1 a mx ~all” .

The next step is the DKIM. Basically, DKIM attaches a ‘signature’ to the message in your emails. Not literally, of course – this ‘signature’ is in the code of the message itself. The DKIM has to be generated for you uniquely. We are developing a tool that automatically generates it for you in the system, but the current way to do that is to message

Once you receive the DKIM, include it in your DNS settings.

Also, Inbox settings sometimes play a large role in this – they may choose to filter out any non-business-related content(it sometimes might be the case with business inboxes). You should also avoid any illicit-sounding terms like “Male enhancement pills”, “Work from home”, “Make money instantly”, because they also might  alert the inbox that you’re sending spam.
