It is a fair question, and most agencies answer it badly, because the honest answer costs them a clean upsell. So here is the straight version, including the part that is not in our favor. Whether your marketing agency should host your website comes down to one idea: when something breaks, who is responsible for fixing it, and how fast can they actually do it.
The real case for it: one team, one point of responsibility
When the same people who built your site also host it, there is no finger-pointing. The site goes down at 6 p.m. on a Friday, and there is exactly one number to call, and the people who answer already know your setup. Think of it like insurance. If your site gets hacked, or a plugin update takes it down, or it just needs to be rebuilt, that is on the team that owns the whole stack, not on you to coordinate between a host and a builder who each swear it is the other one's fault. For a business owner who does not want to become their own IT department, that single point of responsibility is the whole value.

The real cost tradeoff, stated plainly
Agency hosting is usually not the cheapest line item you could find. You can absolutely get a bargain host for a few dollars a month, and if all you want is the lowest possible bill, that is the move. What you are actually paying the agency for is not server space, it is the response. You are paying so that when something goes wrong, a person who knows your business fixes it quickly, instead of you filing a ticket into a queue and hoping. That is a real tradeoff worth naming: a little more per month in exchange for speed and accountability when it counts. For some owners that is obviously worth it. For others it is not, and a good agency will tell you which one you are.
The honest limit: hosting is not a strategy
Here is the part most hosting pitches leave out. Moving your site onto a better server will not, by itself, get you more leads. Hosting protects and maintains what you have built; it does not market it. If your site is not ranking, not converting, or not built to turn visitors into inquiries, better hosting changes none of that. Anyone who sells you hosting as if it will fix your marketing is overselling. It is the foundation the house sits on, not the house. Worth having, easy to overvalue.
So how do you actually decide?
Ask three questions. First, when my site breaks, how fast do I need it back, and who fixes it today? If the honest answer is "I have no idea," that alone is a reason to consolidate. Second, do I want one team accountable for the whole thing, or am I comfortable being the middleman? Third, is the price difference small enough that the peace of mind is worth it? There is no universally right answer. There is only the right answer for how you run your business and how much of this you want to own yourself.
The takeaway
Should your marketing agency host your website? If you value one accountable team and a fast fix when something breaks, yes, and the modest premium buys you real peace of mind. If you only care about the lowest monthly bill and you are comfortable managing the pieces yourself, no. Just do not confuse hosting with marketing: one keeps the lights on, the other brings people through the door.
