Per-contact pricing bills you by how many unique people you have messaged, so your cost rises with your reach — the month a Reel performs is the month your bill goes up. For a creator with a large audience and modest revenue per person, that is the wrong way round. Flat pricing removes the link entirely: Tadlo charges ₹249 a month whether you message fifty people or fifty thousand.
This is the dominant billing model in Instagram automation, and it is worth understanding before you commit rather than after your first good month.
Tadlo's free plan is the most generous in the category — unlimited DMs and unlimited automations, against ManyChat's 25 contacts and a category norm of 500 to 1,500 DMs a month. That is the alternative this page is arguing toward, and the numbers below are why.
How the meter works
You are charged by contacts, subscribers, or active users depending on the vendor's term for the same thing: unique people your automation has messaged. Send a DM to 900 people and you are on a 1,000-contact tier. Send to 1,100 and you move up.
Two details do most of the damage, and neither is prominent on pricing pages.
Reset behaviour. On some plans a contact counts once and stops. On others, someone who messaged you in March still occupies a slot in September. If contacts accumulate, your bill ratchets upward and quiet months do not bring it back down. This is the single most important question to ask, and the answer is rarely on the pricing page.
What counts as a contact. Usually anyone who received a message, whether or not they replied, clicked, or bought. A thousand people who commented a keyword and never opened the DM are a thousand contacts.
Why the bill jumps in a good month
The mechanics are simple and the timing is unfortunate.
Your posts do modestly, you sit around 800 contacts, you are comfortable on a small plan. One Reel does five times your usual numbers and produces three thousand keyword comments. Those three thousand people are now contacts. Your bill moves up a tier, possibly two.
Nothing has gone wrong — this is the model working as designed. But the cost lands in the month you succeeded, before any of that reach has converted into revenue. If you are a creator, the value of those three thousand people is diffuse and slow. The bill is neither.
The behavioural effect is the real problem. Creators on per-contact plans start hesitating before posting the thing most likely to perform, or narrowing their keyword to reduce comment volume. Optimising your content around your tooling bill is a bad position to be in.
What this costs you in real numbers
Take a creator whose posts normally produce about 600 keyword comments a month, with one Reel a quarter that does five times that.
| Month | Contacts | Per-contact plan | Tadlo |
|---|---|---|---|
| Normal month | 600 | Whatever tier 600 contacts falls into | ₹249 |
| Good month | 3,000 | A higher tier: 3,000 contacts is a different bracket | ₹249 |
| Month after, on an accumulating plan | 3,600 retained | Still the higher tier, because the contacts did not reset | ₹249 |
The third row is the one people do not see coming. On plans where contacts accumulate rather than resetting, the good month raises your floor permanently. Your bill does not come back down when your reach does.
Tadlo's column does not move, because there is nothing in it that responds to volume. Free, ₹249 and ₹399 a month, unlimited DMs on all three including the free plan.
When per-contact pricing is worth paying
It is the right model when each contact carries identifiable revenue — B2B where a conversation is worth hundreds, or ecommerce with a solid average order value. And per-contact tools are usually multi-channel platforms covering Messenger, WhatsApp, SMS and email, so you are often buying more product rather than simply a worse deal.
If that is you, buy one. If you are a creator with a large audience, low revenue per person and unpredictable spikes, you are paying a variable cost for something that does not vary in value — and that is the entire case for switching.
What free tiers do under this model
Free tiers on per-contact tools are usually capped by contacts rather than messages, and those caps have tightened across the category.
That change is why a large part of this category currently exists. Most of the "ManyChat alternatives" content published in 2026 is farming that single decision.
What flat pricing actually removes
Flat pricing charges a fixed monthly amount regardless of volume. Three things follow, and they are the reason to switch.
Your bill stops tracking your success. The post that reaches fifty thousand people costs exactly what the post that reached five hundred did.
The free plan stops being a countdown. Tadlo's free plan includes unlimited DMs and unlimited automations, with the follow gate included rather than held back for a paid tier. The upgrade trigger is branding and connected accounts, not message count, so a Reel that performs does not force a decision at the worst possible moment.
You stop optimising content around your tooling bill. This is the one nobody mentions. Creators on per-contact plans start narrowing their trigger keyword to hold comment volume down, or hesitating before posting the thing most likely to perform. That is a bad position to be in and it is invisible until you are already in it.
Tadlo's plans are ₹0, ₹249 and ₹399 a month. No per-contact meter, no monthly message cap, no contact counter that ratchets upward.
The boundary, so you can rule yourself out quickly: Tadlo is Instagram-only. No Messenger, no WhatsApp, no SMS, no email sequences, no ecommerce integrations. If you need those, buy a multi-channel platform and this argument does not apply to you. If Instagram is where your volume actually is, there is no version of the arithmetic where a volume-linked bill beats a fixed one.
Questions to ask before you commit
- Do contacts reset monthly, or accumulate?
- Does someone count as a contact if they never reply?
- What happens when I exceed the tier — automatic upgrade, or does sending stop?
- Is the advertised price monthly or annual?
- What would my bill have been last month at my actual comment volume?
That last one is the only question that produces a real number. Work it out before you pick, not after.
The broader comparison across the category is in what Instagram DM automation actually costs.
Tadlo's answer to all of this is structural rather than a better rate: a flat monthly price, unlimited DMs and unlimited automations, and no contact counter that ratchets upward after a good month. The number you agree to when you sign up is the number twelve months later, whatever your reach does in between.
Frequently asked questions
What is per-contact pricing?
A billing model where you pay according to how many unique people your automation has messaged in a period, rather than a fixed monthly amount. Vendors may call these contacts, subscribers or active users. Your cost rises as your reach rises.
Why did my Instagram automation bill increase?
Most commonly because a post performed well and pushed you into a higher contact tier. On per-contact pricing, everyone who received a DM counts, whether or not they replied or clicked. On plans where contacts accumulate rather than resetting monthly, the increase persists even after your volume returns to normal.
Do contacts reset every month?
It depends on the vendor and it is frequently not stated on the pricing page. Some plans count a contact once within a billing period; others retain them until a manual clear or an archive action. Ask before committing, because accumulating contacts mean your bill ratchets upward and quiet months do not reduce it.
Is per-contact pricing bad?
No, it is a mismatch for some users rather than a bad model. It suits businesses where each contact carries identifiable revenue, and per-contact tools are often multi-channel platforms offering considerably more than Instagram automation. It fits poorly when you have a large audience, low revenue per person, and unpredictable spikes — which describes most creators.
Which Instagram tools use flat pricing?
Flat-priced options tend to be Instagram-only rather than multi-channel, which is the tradeoff. Tadlo charges a fixed monthly price — ₹0, ₹249 or ₹399 — with unlimited DMs on every plan including the free one, and no contact meter of any kind. Verify current models directly with any vendor, since pricing changes.
Is flat pricing cheaper than per-contact pricing?
It depends on volume, and the crossover comes sooner than most people expect. Below a few hundred contacts a month the difference is small. Above that, per-contact tiers climb while a flat plan does not, and on plans where contacts accumulate rather than resetting, a single strong month raises your bill permanently. Work out what you would have paid last month at your actual comment volume — that number decides it.
