You signed up for lemwarm.
It worked for a while.
But now you’ve got more clients and inboxes to deal with - giving you deliverability headaches.
You know it’s time to upgrade to an email deliverability tool built for serious senders.
But what’s the best lemwarm alternative for agencies and SaaS platforms?
Meet Mailivery, an email deliverability tool that doesn’t charge you per inbox, offers founder-led support and provides the most flexible and complete email warm-up API on the market.
lemwarm makes you pay per inbox. With monthly billing, that’s at least $29 per inbox each month (lemwarm’s Essential plan).
That means:
If you must warm up 50 email accounts…
You’ll pay $1450/month.
Mailivery’s pricing works differently. It does not punish you for scaling your warmup. Instead, you can warm up unlimited inboxes with a cap on daily warmup emails.
For example:
Mailivery’s business plan allows you to send 2000 warm-up emails/day for a mere $199/month. It becomes even more cost effective if you opt for yearly billing: $149.25/month.
lemwarm’s Essential plan lacks many of the advanced features of their Smart plan, such as:
Mailivery gives you access to ALL features.
No matter what plan you select, you can use everything Mailivery has to offer, such as:
Purchasing a higher-level Mailivery plan just gives you more of the good stuff, like more daily warm-up emails and email verification credits.
Email deliverability starts with your email list. You should verify each email before using it.
If you send to unverified emails, you risk:
Unfortunately, lemwarm does not offer an email list verifier. You’re at the mercy of third-party tools for this essential step in maintaining or improving email deliverability.
Mailivery uses a unique 2-layer verification process:
Step 1️⃣ : It checks each address against a proprietary database of more than 100 million bad emails and spam traps
Step 2️⃣ : It then runs a standard technical verification check to ensure the cleanest and safest list for cold outreach
lemwarm seems to have a solid premium warm up network in over 150 countries. However, it doesn’t provide clear info on their warm-up pool.
With Mailivery, your warm-up emails go to a network of real inboxes only. No fake or junk mailboxes used by some other warmup services.
Mailivery’s inbox pool is actively monitored, diversified, and optimized for real-world sending behavior. And no AI agent email warmup. Mailivery uses only SMTP and IMAP for more human-like interactions.
lemwarm labels all email warmup emails with “lemwarmup.”
The presence of this word in the subject line makes it shockingly easy for email providers to detect warm-up emails.
When email providers know they’re dealing with warmup emails, instead of real human email interaction, the whole warmup process could fall apart.
Mailivery does it smarter: each user gets a unique filter code, meaning you can still filter out the emails, but they will not alert providers to potential warm-up emails.
The result?
Your domain reputation stays cleaner, and warm-up does what it should: boost inbox placement, not hurt it.
lemwarm has a solid support team.
However, the larger product ecosystem means less room for custom tweaks.
Mailivery’s team is hands-on. Agencies and SaaS partners regularly help improve the product.
You’re not just using the tool. You’re shaping it.
lemwarm does not offer a standalone API for embedding warm-up natively into other software.
Mailivery does, and it’s the most flexible email warm-up API on the market.
You’re not stuck with cookie-cutter settings or limited controls.
You can connect any inbox type, control warm-up speed, create custom templates, and fetch full warm-up performance data and inbox health indicators.
With Mailivery’s API, you can add email warm-up to your app, your way.
