Comparison: Dedicated IP pricing across 5 major ESPs - a cost analysis.

Your point about the total cost picture is correct. The monthly IP fee is just the entry point.

You need to model the operational costs. For Provider C, that $20 IP becomes $119/month with warm-up, putting it above Provider A before you even factor in volume. Provider B's "unlimited" is attractive, but you must verify if that means truly unlimited sending on that IP or if there are throttling limits not listed.

The commitment term from Provider A is a significant lock-in risk, but it often correlates with better support for reputation issues. I'd recommend building a simple spreadsheet projecting costs over 12 and 24 months, including your expected volume growth and the warm-up service cost if you can't manage it internally.

Yeah, the spreadsheet model is the only way to make a real decision here. You're spot on about the lock-in risk with Provider A, but that support trade-off is huge. We've had threads where folks on short-term contracts couldn't get the same level of urgent reputation help as those on annual plans.

One thing I'd add about the "unlimited" claim: always ask for the AUP (Acceptable Use Policy) document. Sometimes "unlimited" means no hard cap, but they'll flag you for "abnormal" growth or high complaint rates, which essentially throttles you. A true unlimited IP is rare.

This is a great breakdown, thanks for sharing it. I've been looking at similar options for our Salesforce marketing sends.

You're right that the warm-up cost changes everything. That extra $99 for Provider C feels like a hidden fee if you don't have the internal know-how. I'd lean towards a slightly higher base cost if the reputation support is bundled.

A question for the more experienced folks here: how do you factor in the included volume? Is 100k per IP a standard benchmark, or is Provider D's 10k starting point a red flag for potential overage charges?

You're missing the forest for the spreadsheet. The "lock-in risk" with Provider A isn't just a risk, it's the whole point. They aren't selling you an IP; they're selling you a one-year contract for reputation babysitting, disguised as an IP. That's why the support correlates.

And modeling operational costs based on listed add-ons like warm-up is naive. The real operational cost is the internal time spent when something goes sideways and you find out your "unlimited" provider defines support as a weekly check-in email. The cheaper the base fee, the more you're on your own.

Welcome to the marketing side, where pricing is a feature, not a cost. Your table is a decent start, but you're already falling for the classic trap.

You say "the base IP cost is just one part," but that implies the listed parts are the real costs. They're not. The real cost is the penalty for getting it wrong. Provider E's $120 fee includes IPM tool access because without it, you're flying blind and will inevitably crash. That "included" cost is the whole product. Provider C's $20 IP is a liability, not a bargain.

Your instinct about higher base cost is correct, but for the wrong reason. It's not about bundled warm-up; it's about bundled accountability. Cheap providers sell you rope. The expensive ones sometimes hand you a manual.

Ah, the mythical "unlimited" claim. Asking for the AUP is good advice, but even that's often written in legalese designed to give them maximum wiggle room.

The more telling document is their internal policy on complaint rates. Many define "abnormal" as anything that triggers their own risk algorithm, which they'll never share. So you're right, it's a soft throttle, but it's worse - it's a secret throttle you can't measure against until they pull it.

As for the support trade-off with annual contracts, I've seen that too, but let's call it what it is: a loyalty reward, not a feature. They don't *can't* provide the same support to monthly clients, they *won't*. It's a deliberate business choice to upsell the commitment.

Exactly. The loyalty reward framing is key. I've seen providers with identical SLAs on paper for monthly vs annual customers, but the actual response times and engineer access were night and day. It's not a technical limitation, it's a resource allocation choice dressed up as a feature.

And on the secret throttle, the truly devious part isn't the algorithm. It's that once you trigger it, they'll point to a vague clause in the AUP you violated and tell you to "reduce sending to normal levels," without ever defining what that is. So you're left guessing, sending less and less until the alerts stop, effectively setting your own limit under duress.

It's less a throttle and more a hostage negotiation.

You've hit on the hostage negotiation aspect, but I'm surprised you're still calling it a "secret throttle." It's not secret, it's standard operating procedure. The goal isn't to manage your volume, it's to manage their liability.

That "vague clause" is the escape hatch for their SRE team. They don't want to define "normal levels" because then they'd have to support you up to that line. The ambiguity *is* the product. It lets them preserve their own infrastructure's reputation by making your problem yours alone to solve, through guesswork.

I'd argue the cheaper the provider, the more they rely on this model. Their margins are in the ambiguity.

Great question about the included volume. I was wondering the same thing, especially when you see such a huge spread between providers. The 10k starting point for Provider D felt weirdly low to me too, like maybe it's a trap for overage fees later.

But then I saw a thread last week where someone mentioned that 100k isn't really a standard. It's more about the type of mail. For big batch promotional sends, 100k makes sense. But if you're doing transactional emails, your volume is steadier and you might not need that high of a ceiling. Is your Salesforce use case more for big campaigns, or is it for automatic receipts and alerts? That might change which benchmark is actually relevant for you.
