When email deliverability is worth the effort

It comes up on almost every project, usually later than it should. Email deliverability is not free, and pretending otherwise leads to bad decisions.

The realistic threat for most small businesses is automated and opportunistic, not targeted. Write the reasoning down alongside the decision, because the reasoning is what changes first.

When it is worth it

Authentication records decide whether mail reaches the inbox. This is the sort of thing that compounds, quietly, in both directions. Most teams find the first pass takes an afternoon and the maintenance takes minutes a month.

When it is not

If nothing downstream depends on it and nobody is complaining, it can wait. Small and consistent beats large and occasional here.

How to decide

How to tell if yours is fine

Security is a maintenance habit rather than a purchase, which is why it drifts. Three things worth confirming about email deliverability before you move on:

• Someone can say what the current setup is without going to look
• Monitor bounces before a campaign, not after — and you know whether that is true here
• There is a way to tell whether the last change to this helped

If you want a second opinion on how yours is set up, ask.
