Short answer: Constant Contact limits emails per month, not contacts. You can send 10× your contact tier on Lite, 12× on Standard and 24× on Premium each billing month (at 0–500 contacts: 5,000 / 6,000 / 12,000 emails). Going over doesn't stop sending; each extra email costs $0.002 ($2 per 1,000). Automated emails don't count. There's no contact limit on any plan, the free trial allows 100 sends in 30 days, and test emails to unverified addresses are capped at 50 per 24 hours.

Emails per billing month = multiple × the top of your contact tier, with the monthly-billing USD price in brackets (from our Constant Contact plans data, checked 2026-11-03). Your contact tier is the highest number of active email contacts you've had, so the allowance follows that peak, not today's list size (KB 51160). You can see your current usage on the Billing tab in your account settings.
What counts toward the limit
- One send = one email to one contact. A campaign to 2,000 contacts uses 2,000 sends. Bounced emails still count (KB 46046).
- Automated emails don't count: welcome emails, abandoned-cart reminders and automated email series are excluded from the allowance and from overage.
- Scheduled campaigns count, including automatic resends to non-openers. Resends go out on a different day, so they can fall into the next billing cycle, and they're not shown on the Reporting tab, so check the Billing tab for the real count.
- To stay under it Constant Contact suggests removing disengaged contacts (bounces count), sending to segments instead of the whole list, and using dynamic content instead of several versions of one email.
What going over costs
Sending never stops at the allowance. Each send above it costs $0.002, i.e. $2 per 1,000, deducted from your prepaid balance if you have one or billed separately. Constant Contact's own example: Lite at the 2,500 tier allows 25,000 sends; 40,000 sent → 15,000 over × $0.002 = $30 (KB 46046). Here is the same arithmetic for a 2,500-contact list at common frequencies:
| You email every contact | Sends needed | Lite overage | Standard overage | Premium overage |
|---|---|---|---|---|
| Weekly (4×/mo) | 10,000 | No overage | No overage | No overage |
| 2× a week (8×/mo) | 20,000 | No overage | No overage | No overage |
| 3× a week (12×/mo) | 30,000 | +$10 (total $60) | No overage | No overage |
| Daily (30×/mo) | 75,000 | +$100 (total $150) | +$90 (total $165) | +$30 (total $180) |
Our calculation: $0.002 × sends above 25,000 / 30,000 / 60,000 (the 2,500-tier allowances), total = monthly plan price + overage, USD, monthly billing. Automated emails are left out because they don't count. Which plan is cheapest for your list and frequency: Constant Contact plans.
Contact limits
Constant Contact's billing article is explicit: "There is no contact limit for each email plan." Every plan uses the same contact tiers, and the tier sets your price and your send allowance. Deleting contacts doesn't lower the tier, and SMS-only contacts don't count toward it (KB 51160). If your list grows into a higher tier during the month, the higher price shows up on the next bill.
Free trial limits
- 30 days, 100 email sends in total; each email to a unique contact counts as 1, so one campaign to 100 contacts uses the whole allowance (KB 5549).
- Contacts: upload as many as you want and create segments.
- Other campaign types (automated emails, landing pages, Survey Pages, Events) can be built during the trial but only published after you upgrade.
- When it ends: it can't be paused or cancelled and ends by itself after 30 days; your contacts, drafts and reports stay in the account.
The pricing page only says "Start trial" and "no credit card required" without a length; the 30-day figure and the 100-send cap come from the Knowledge Base article. Is there a free plan instead? No, see Is Constant Contact free?
Test email limits
- Verified addresses (addresses verified in your account): unlimited tests.
- Unverified addresses: up to 50 test emails in 24 hours. Reach it and the test feature locks for 24 hours for all addresses, including verified ones; it unlocks one test at a time, 24 hours after each unverified test was sent (KB 6096).
- Per test: up to 5 addresses. Unsubscribe links, personalization and dynamic content don't work in tests, so Constant Contact suggests sending a copy to a small review list instead (KB 5254).
How fast Constant Contact sends (and staging)
| List size | Average send time | Maximum |
|---|---|---|
| Under 50,000 contacts | 12–15 minutes | 30 minutes |
| 50,000–200,000 contacts | 20–27 minutes | 60 minutes |
| 200,000–500,000 contacts | 28–46 minutes | 2 hours |
| 500,000–1 million contacts | 45–93 minutes | 4 hours |
| 1–8 million contacts | 110–290 minutes | 6 hours |
From KB 6041. New or larger lists emailed for the first time may go through "staging": Constant Contact releases the email in small portions, watches bounces and spam complaints, and generally finishes within 24–48 hours; with poor results it can slow or stop the mailing (KB 7402).
Constant Contact vs Mailchimp send limits
| Plan level | Constant Contact | Mailchimp |
|---|---|---|
| Entry | Lite 10× contacts | Essentials 10× contacts |
| Middle | Standard 12× | Standard 12× |
| Top | Premium 24× | Premium 15× |
| Free | No free plan (trial: 100 sends) | 500 a month, 250 a day |
Mailchimp figures from our Mailchimp sending limits guide. The two platforms handle going over differently: Constant Contact bills $0.002 per extra send, Mailchimp adds contact blocks.
Where Constant Contact's pages disagree
- 5× multiple: the English send-allowance article says customers can send "up to 5, 10, 12, or 24 times" their contact tier, but the current pricing page and plan comparison only show 10× (Lite), 12× (Standard) and 24× (Premium), and the Spanish version of the same article (same publish date) lists only "10, 12 o 24 veces". We searched the Knowledge Base (legacy Email / Email Plus / Core / Plus plans, pricing-change FAQ, the separate Starter Email plan) and no article says which plan has 5×, so we don't assign it. The Starter Email account article mentions a monthly send allowance but gives no number. If your Billing tab shows a different allowance, that is the number that applies to you.
- Trial length: the pricing page doesn't state it; the Knowledge Base says 30 days.

FAQ
How many emails can I send with Constant Contact?
It depends on your plan and contact tier. Each billing month you can send 10× (Lite), 12× (Standard) or 24× (Premium) the top of your contact tier: at 0–500 contacts that is 5,000, 6,000 or 12,000 emails; at 50,000 contacts 500,000 on Lite up to 1,200,000 on Premium. One send = one email to one contact, and bounces count (Constant Contact KB). Sending doesn't stop at the limit; extra sends cost $0.002 each.
How many emails can you send with Constant Contact Lite?
10× your contact tier a month: 5,000 at 0–500 contacts, 10,000 at 1,000, 25,000 at 2,500, 100,000 at 10,000. That is roughly 10 emails per contact per month (about twice a week). Above that, each extra email costs $0.002 ($2 per 1,000).
How many free emails can I send with Constant Contact?
Constant Contact has no free plan. The 30-day free trial allows up to 100 email sends in total (an email to 10 contacts uses 10), though you can upload as many contacts as you want. Automated emails, landing pages and other campaign types can be built in the trial but only published after you upgrade (Constant Contact KB).
What happens if I go over my Constant Contact send allowance?
Your emails still go out. Each send above the allowance costs $0.002 (= $2 per 1,000), taken from your prepaid balance if you have one or billed separately. Constant Contact's own example: 25,000 allowed, 40,000 sent → 15,000 × $0.002 = $30 (Constant Contact KB).
Do automated emails count toward the Constant Contact email limit?
No. Welcome emails, abandoned-cart reminders and automated email series are excluded from the send allowance and overage. Campaigns you schedule, including automatic resends to non-openers, do count, and a resend can land in the next billing cycle (Constant Contact KB).
Is there a contact limit on Constant Contact?
No: "There is no contact limit for each email plan" (Constant Contact KB). You pay by contact tier instead (published tiers up to 50,000; above that, Contact Sales). The tier is the highest number of active email contacts you've had, deleting contacts doesn't lower it, and SMS-only contacts don't count.
Is there a limit on Constant Contact test emails?
Tests to verified addresses in your account are unlimited. Tests to unverified addresses are limited to 50 in 24 hours; hit that and the test feature locks for 24 hours for all addresses, unlocking on a rolling basis. Each test can go to up to 5 addresses (KB 6096, KB 5254).
How many emails can Constant Contact send at once?
There is no per-send cap in the sources: a campaign goes to the whole list you pick, and the monthly allowance is the limit that matters. Constant Contact says lists under 50,000 typically finish in 12–15 minutes (30 minutes max), up to 1–8 million contacts in 110–290 minutes (6 hours max) (KB 6041). New or large lists emailed for the first time may be "staged" and released over 24–48 hours (KB 7402).
What are the Constant Contact API limits?
The V3 API allows 10,000 requests per day and 4 per second per API key, resetting at 00:00 UTC; over the limit you get HTTP 429. Details: Constant Contact plans → API rate limits.
