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.
