How to budget for email marketing on send-based pricing

Bluey Email team·Updated 2026-09-11·9 min read
The short version

On send-based pricing, your email budget is one multiplication: the number of people you email, times how often, gives your monthly sends — and your plan is the smallest tier that covers them. Size it on your busiest normal month rather than an average, plan separately for peak months, and add paid extras such as a dedicated IP only when your volume justifies them. On Bluey, one detail changes the arithmetic at the low end: below 20,000 sends a month your contact list is capped at your send volume, while from 20,000 upwards contacts are unlimited.

Per-contact pricing makes budgeting a forecast of how big your list will be. Send-based pricing makes it a decision about how often you email. The second is much easier to control.

The budgeting method on this page works for any send-priced platform. The figures are Bluey’s, because a budget with real numbers in it is more useful than one with placeholders — and because the one quirk in how Bluey counts contacts at the low end changes the answer for small lists.

The one calculation

Take the number of people you actually email — not the size of your database, the size of the segments you send to — and multiply by how many times a month each of them receives something. Add your automated flows, which are easy to forget because nobody schedules them.

  • Campaign sends = contacts you email × campaigns per month.
  • Flow sends = new subscribers × emails in your welcome series, plus carts × cart emails, plus orders × post-purchase emails. Estimate from last month.
  • Monthly sends = campaign sends + flow sends. Round up to the next tier.

A shop with 20,000 subscribers
20,000 subscribers emailed five times a month is 100,000 campaign sends. Add roughly 3,000 flow sends from welcome and cart emails, and the month comes to about 103,000. That is just over Bluey’s Grow tier at 100,000 sends (₹3,000 or $36 a month), so there are two honest options: leave the least engaged 3,000 contacts out of one campaign and stay on that tier, or move to the 250,000 tier (₹7,000 or $84) for headroom. The first is usually the better email programme as well as the cheaper one. The list size itself never appears in the bill, because Grow includes unlimited contacts.
Before committing to a figure, run it through the email cost calculator with your real numbers. It also shows what the same sending pattern costs on a per-contact plan, which is usually the fastest way to see whether the model suits you at all.

The rule below 20,000 sends

Bluey is priced on sends, but at the smallest volumes the contact list is capped at your send volume: a plan that includes 6,000 sends a month holds up to 6,000 contacts, and 10,000 sends holds 10,000. From 20,000 sends a month upwards, contacts are unlimited.

In practice this only matters for one pattern: a list that is larger than what you send in a month on a small plan — say 9,000 contacts where you only email a 5,000-person segment. On the 6,000-send tier the list would not fit, so the 10,000-send tier is the right plan even though you do not need the sends. Everyone else can ignore the rule, because at small volumes most people email their whole list at least once a month anyway.

Budgeting for peak months

Most businesses have one or two months that send far more than the rest — November for retail, December for fundraising, a launch month for software. Budget the plan on your busiest normal month, then treat the peak as its own decision:

  • Move up a tier for the peak month and back down afterwards, if your peak is two or three times your normal volume. You pay for the capacity in the month you use it.
  • Segment the peak instead, if the extra volume would mostly go to unengaged contacts. It usually would — and those are exactly the sends that raise complaint rates in the week you can least afford it.
  • Do not buy a year of headroom to cover one month. The email calendar guide shows how to plan the peak month by month so the jump is deliberate rather than a surprise.

What else belongs in the budget

  • A dedicated IP — ₹2,000 or $30 a month on Grow, Business and the transactional Pro plan. Worth it once you send steadily at high volume and want your reputation to be yours alone; not worth it at low volume, because a new IP needs consistent traffic to build any reputation at all.
  • Transactional email — receipts, password resets and failed-payment notices. Every Bluey marketing plan can send transactional email alongside campaigns. The separate transactional API plans exist for high-volume transactional sending, priced on their own and kept apart from campaign traffic so a spike never delays critical mail.
  • Seats — 2 on Spark, 4 on Grow, unlimited on Business. The seat count is often what moves a team up a plan before the send volume does.
  • Your time — the real cost of most email programmes. A tool that saves one person two hours a week is worth more than a cheaper one that does not.

Budgeting inside a Bluey plan

Once you are on a plan, three habits keep the budget where you set it:

Keeping the bill predictable

Review monthly sends against your tier once a month, not when the invoice arrives
Send campaigns to engaged segments by default, and the full list only on purpose
Suppress contacts who never engage — on send-based pricing they cost nothing to store, but they still cost sends every time you include them
Move tiers ahead of a known peak month, then back down
Check the automation allowance (3 on Spark, 25 on Grow) before planning a new flow — that limit moves teams up a plan more often than send volume does

Budget FAQ

How much should a small business spend on email marketing?

Enough to cover your real monthly sends with a little headroom, and no more. On send-based pricing that is a direct function of how many people you email and how often, so the honest answer is to run the multiplication rather than use a percentage-of-revenue rule. For many small businesses it is a single-digit number of dollars or a few hundred rupees a month.

Is send-based pricing always cheaper than per-contact pricing?

No. It is cheaper when your list is large relative to how often you email it, which describes most businesses. If you email a small list every day, per-contact pricing can come out ahead. The cost calculator shows where the two cross for your own numbers.

Do automated flows count towards my sends?

Yes. Every email sent counts, whether a campaign or a flow step. Flows are easy to leave out of a budget because nobody schedules them, so estimate them from last month's signups, carts and orders.

What happens if I exceed my monthly sends?

Plan limits and what happens at the edge of them are set out on the pricing page, which is the current source rather than this guide. The better habit is to review sends monthly and move up a tier ahead of a known busy month.
