When Unlimited Emails Actually Matter
The biggest selling point for Mailercloud is unlimited emails. But does that actually matter for your business?
If you're sending weekly newsletters and the occasional promotion, you won't hit Constant Contact's 12x limit. At 10k contacts, that's 120k emails per month - about 30 sends per subscriber monthly. Most businesses don't come close to this.
But if you're running daily engagement campaigns, multiple segmented sequences, or high-frequency transactional-style marketing, unlimited sending becomes valuable. E-commerce stores during holiday seasons, media companies with daily digests, or agencies managing multiple clients can easily burn through 120k sends.
The math: If you send 5 emails per subscriber per month, you're at 50k emails. If you send 10 emails per subscriber monthly (aggressive but not uncommon for e-commerce), you're at 100k. You'd hit the Constant Contact limit at 12 sends per subscriber monthly.
For context, ConvertKit and MailerLite also cap sending, while Mailchimp charges based on sends. Truly unlimited email at $50/month is rare.
The Support Gap Is Real
Constant Contact's phone support isn't just a nice-to-have - it's often the deciding factor for non-technical users.
When you're stuck configuring DNS records for email authentication, or your automation isn't triggering correctly, being able to call someone who walks you through it step-by-step is huge. Constant Contact's support team is known for patience with beginners.
Mailercloud only offers email support. You'll submit a ticket and wait for a response. For urgent issues (like a campaign that needs to go out today), this can be frustrating.
The trade-off is clear: save $30/month and handle problems yourself, or pay more for hand-holding. If you're technical or have a developer on your team, Mailercloud's support is probably fine. If you're a small business owner doing this yourself for the first time, Constant Contact's phone support is worth the premium.
Similar dynamics exist with other platforms - Brevo offers chat support at lower tiers, while ActiveCampaign charges extra for premium support.
Event Management Changes the Game
If you run events - conferences, fundraisers, workshops, webinars, networking meetups - Constant Contact's built-in event tools are a killer feature.
You can create event landing pages, manage registrations, sell tickets, send automated reminders, and track RSVPs all inside Constant Contact. After the event, attendees are automatically added to your email list for follow-up campaigns.
Mailercloud offers none of this. You'd need to use a separate event platform like Eventbrite, then manually sync attendees back to your email list. That's extra cost, extra work, and more room for things to break.
For event-heavy organizations (nonprofits, community groups, professional associations), this alone justifies Constant Contact's higher price. For businesses that never run events, it's a feature you're paying for but won't use.
If you're evaluating platforms for event marketing, also check out GetResponse, which includes webinar hosting, and Eventbrite's email tools if events are your primary focus.
AMP Emails: Mailercloud's Hidden Weapon
Mailercloud supports AMP for Email, which lets you add interactive elements directly inside emails. Think:
- Forms that subscribers fill out without leaving their inbox
- Image carousels they can swipe through
- Accordions that expand/collapse
- Live inventory updates for e-commerce
This is legitimately cool and not widely supported. Gmail, Yahoo, and some other clients support AMP, though Apple Mail and Outlook don't.
Constant Contact doesn't support AMP at all. Neither do most competitors - Klaviyo, Omnisend, and Drip all lack AMP support.
The catch: AMP emails require extra development work. You can't just use a drag-and-drop builder - you need to understand AMP syntax or hire someone who does. For most small businesses, this feature goes unused.
But if you're technical and want to experiment with interactive emails, Mailercloud gives you that option at an affordable price point.
Event Marketing
Constant Contact includes event marketing tools - create events, manage registrations, send invitations. For organizations hosting events regularly, this integration is valuable. Mailercloud has no event marketing.
Support
Constant Contact offers phone support. Mailercloud offers email and chat. For less technical users who prefer personal assistance, Constant Contact provides more comfort. Check our email deliverability guide for best practices.
Value Assessment
Constant Contact's premium pays for event marketing, social tools, and phone support. If you use these, the price is justified. For email-only marketing, Mailercloud delivers essentials at better value.
Use-case matchups
| Situation | Better fit | Why |
|---|---|---|
| You need affordable high-volume email campaigns | Mailercloud | Mailercloud is cheaper in the 10k-contact scenario and supports unlimited sends. |
| You need phone support and beginner hand-holding | Constant Contact | Constant Contact has phone, chat, and email support in the page data. |
| You run events, fundraisers, classes, or registrations | Constant Contact | Event management is a specific Constant Contact advantage here. |
| You want AMP email experiments | Mailercloud | Mailercloud supports AMP, while Constant Contact does not. |
| You need subscription lifecycle email for SaaS | Sequenzy | Sequenzy is the option here built around Stripe and transactional plus marketing email. |
Best Fit by Small-Business Workflow
Best email marketing tool for affordable high-volume campaigns
Mailercloud fits teams that want low-cost campaign sending, unlimited sends, and AMP experiments without paying for event-management extras. It is the better fit when the budget question is campaign volume, not support, local events, or broad small-business guidance.
Best email platform for events, classes, and beginner support
Constant Contact is the better fit when phone support, guided onboarding, event promotion, registrations, and local-business workflows matter. Choose it when non-technical staff need a proven workflow for newsletters, classes, fundraisers, and community outreach.
Best email platform for SaaS subscription lifecycle
Sequenzy fits when subscription billing events and transactional plus marketing email are the reason for switching. It is more useful when Stripe, product activity, and lifecycle state should trigger the next message.
Pricing reality
The page data shows Mailercloud at $50/month and Constant Contact at $80/month for 10,000 subscribers. If you only need newsletters and basic automation, that $30/month difference is meaningful.
Constant Contact's premium is easier to justify when event tools, social posting, phone support, and beginner-friendly workflows replace other tools or reduce support burden. If those features go unused, Mailercloud is the better value.
Review signals
The Mailercloud reviews emphasize lower cost and unlimited sends for simple email, while noting that Constant Contact's event features may be missed.
Constant Contact reviews emphasize reliability and nonprofit/event workflows, with the recurring downside of higher pricing and an older-feeling interface. That matches the feature trade-off in the page.
Migration checklist
- Export contacts, unsubscribes, segments, tags, templates, automations, forms, event data, and suppression lists.
- If moving away from Constant Contact, replace event registration, ticketing, and invite workflows before switching.
- If moving to Constant Contact, rebuild high-frequency campaigns around its monthly send limits.
- Reconfigure SPF, DKIM, DMARC, tracking domains, sender identities, and unsubscribe handling.
- Test event reminders, campaign sends, form submissions, and support-critical workflows before launch.
- Keep the old platform active until events, forms, suppressions, and active automations are confirmed.
Decision checklist
- Choose Mailercloud if price, unlimited sending, and AMP experiments matter most.
- Choose Constant Contact if events, phone support, and beginner-friendly setup are central.
- Choose Sequenzy if SaaS billing events and transactional email are the real workflow.
