Mailjet is good for small opt-in programs and weak for true bulk. The free plan caps you at 200 emails a day, paid plans start at $19 a month for 15,000 emails, and a dedicated IP only exists on Premium plans of 100,000+ emails on request. Under roughly 100,000 emails a month it is a fair, simple choice. Above that, shared IPs, quote-only tiers and per-email pricing start to cost you more than they save.
What Mailjet costs and allows
These are the plans on Mailjet's pricing page at the 15,000 email setting, checked in November 2026.
| Plan | Price a month | Emails a month | Daily cap | Contacts | Dedicated IP |
|---|---|---|---|---|---|
| Free | $0 | 6,000 | 200 a day | 1,000 | no |
| Starter | $9 | 8,000 | none listed | 2,000 | no |
| Essential | $19 | 15,000 | none listed | unlimited | no |
| Premium | $29 | 15,000 | none listed | unlimited | 1, on 100K+ plans on request |
| Custom | quote | custom | not listed | not listed | 1, more for sale |
Two details matter more than the headline prices. Unused emails do not roll over, so a quiet month is money gone. And sending past your allowance is billed per extra 1,000 emails, at a rate the page links to rather than shows.
The free plan's 200 a day cap against a modest list
Where Mailjet is a good fit
Mailjet does a few things well, and for the right sender it is a sensible pick.
- Mixed mail from one account. Marketing campaigns and transactional API mail sit in one dashboard.
- Unlimited contacts from Essential up. You pay for sends, not for list size.
- A real free plan. 6,000 a month is enough to test your setup and run a small newsletter.
- Subaccounts on Premium. Up to 20, useful for small agencies.
If you send under 100,000 emails a month to people who asked for them, Mailjet will do the job and you will rarely think about it.
Where it stops working
The limits show up at three points: daily caps on the free plan, shared IPs on paid plans, and the jump to custom pricing.
| Limit | What happens | Who it hurts |
|---|---|---|
| 200 a day on Free | extra mail waits for tomorrow, dropped after 3 days | anyone with a list over a few hundred |
| Hourly limit on new accounts | throttled until a clean week, then ask Support | new senders with a launch date |
| Shared IPs by default | your placement depends on neighbours | senders with a strict inbox target |
| Dedicated IP only at 100K+ | no IP of your own below that | mid-size senders who want control |
| 7-day limit on threshold breach | sending slowed or paused | anyone with one bad list import |
| Custom quote above listed tiers | price unknown until sales calls | high-volume senders |
The 3-day queue on the free plan is the one that catches people. Send 2,000 emails on a free account and, at 200 a day, most of them never leave: Mailjet's own help docs say queued mail is removed after 3 days.
How good is Mailjet's deliverability?
On a clean, opt-in list, it is fine. Mailjet signs your mail with DKIM, supports SPF and DMARC on your domain, and watches its shared pools closely. The weak point is the pool itself. On shared IPs, a neighbour's bad campaign can dent the IP reputation that Gmail and Microsoft see for your mail too.
That is why the tighter you need inbox placement, the more you want your own IP. Mailjet's answer is one dedicated IP on Premium plans of 100,000+ emails a month, on request. Our post on dedicated vs shared IPs explains when that switch pays off.
What tips the balance as volume grows
Mailjet vs the other common options
| Option | Cost at 1M emails a month | IPs | Setup work |
|---|---|---|---|
| Mailjet Premium or Custom | quote, scales with volume | 1 dedicated, on request | low |
| Amazon SES | about $100 plus $24.95 per dedicated IP | shared or dedicated | high, you build bounces and suppression |
| Dedicated SMTP server (Advance) | about $49 hosting after $1,199 one-time | 15 dedicated | done for you |
Amazon SES is the cheapest per email at $0.10 per 1,000, but you build bounce handling, suppression and a sending panel yourself. A dedicated server costs a one-time setup fee, then the monthly bill stays flat whether you send one million or six million. See what 1 million emails a month costs for the full picture.
The verdict, by sender type
Mailjet's fit depends on volume and list type
| You are | Mailjet verdict |
|---|---|
| Small newsletter under 6,000 a month | good, the free plan covers it |
| App or SaaS sending receipts | good, API plus templates in one place |
| Opt-in marketer at 100K to 1M a month | mixed, ask for the dedicated IP and get a quote |
| Over 1M a month | costly, quote-only pricing with per-email growth |
| Cold outreach or bought lists | not allowed, and a fast way to a block |

When to move off Mailjet
Move when two of these are true:
- You send more than 100,000 emails a month and it is still growing.
- You have hit a 7-day limit or an hourly cap at a bad moment.
- You need your own IPs for reputation control, not just one on request.
- Your quote for the next tier is higher than a year of flat hosting.
Keep your list clean before you move. A list that caused a limit on Mailjet causes the same problem anywhere. Our list cleaning guide covers the steps.

Frequently asked questions
Is Mailjet good for bulk email?
Mailjet is good for small to mid-size opt-in programs: newsletters, receipts and simple automations up to roughly 100,000 emails a month. It gets weaker for true bulk. Paid plans run on shared IPs by default, a dedicated IP is only offered on 100K+ Premium plans on request, and anything above the top listed tier is a custom quote.
What are Mailjet's daily sending limits?
The free plan allows 6,000 emails a month with a cap of 200 a day, and Mailjet's help docs say mail over the cap is queued for the next day and dropped after 3 days. Paid plans list no daily limit, but new accounts can be put on an hourly limit until they show at least a week of clean sending.
How good is Mailjet's deliverability?
On a clean list, deliverability is fine, because Mailjet authenticates your domain and polices its shared pools. The catch is the shared pool itself: your inbox placement partly depends on other senders on the same IPs. That is why serious senders ask for a dedicated IP, which Mailjet only offers on Premium plans of 100,000 emails a month and up.
What is cheaper than Mailjet at volume?
At high volume, Amazon SES at $0.10 per 1,000 emails is cheaper on paper but needs engineering. A dedicated SMTP server is the flat-cost option: BulkEmailSetup's Advance plan is $1,199 one-time for 200,000 emails a day, with hosting around $49 a month, so a million emails a month costs the same as ten million.
Does Mailjet limit contacts?
On the low tiers, yes. The free plan stores 1,000 contacts and Starter 2,000. Essential and Premium list unlimited contacts, so the bill follows emails sent rather than list size. That is friendlier than Mailchimp-style per-contact billing, but you still pay more as you mail more often.
Can Mailjet suspend my account?
Yes. Mailjet's help docs describe temporary 7-day limits when an account breaks its acceptable sending thresholds, and full blocks for policy problems such as list sources it does not accept. It does not publish the exact threshold numbers and says it can change them without notice, so treat any bounce spike as a risk to your sending.
