Mailjet can stack overlapping subscriptions for the same sends, and live help is hard to reach the moment a campaign is on the line.
by Alkan Balkaya · Last updated: 2026-06-05Switching from Mailjet to Mailsoftly takes most teams a few hours, not days. You export your contacts, segments, and templates from Mailjet, import them into Mailsoftly, verify your sending domain, and rebuild your automations. Mailsoftly handles the heavy lifting for free, so you move with no downtime and no lost data.
This guide walks through the full migration in order: what to export, how to import cleanly, how to protect deliverability, and what to check in your first week. It is written for marketers and founders, not developers, so every step is something you can do yourself or hand to our team.

Key Takeaways
Teams leave Mailjet for three recurring reasons: cost that climbs as volume grows, a platform built around developers more than marketers, and support that feels distant when a send is at risk. Mailsoftly answers all three with flat pricing, a marketer-first interface, and humans who reply.
Mailjet separates marketing and transactional sending, and add-ons like dedicated IPs, segmentation, and priority support can stack onto your base plan. You can review Mailjet’s current pricing tiers to see how those layers add up. The result is a bill that grows in steps you did not plan for. Mailsoftly keeps every feature in one plan, so the number you sign up for is the number you pay.
Mailjet shines as an API and transactional tool, which is exactly why campaign builders can feel like an afterthought. Email is still one of the highest-return channels in marketing, and HubSpot’s marketing statistics consistently rank it at the top for ROI, so the tool you use to send it should not slow you down. Mailsoftly puts list management, segmentation, and automation in a single, plain interface that a non-technical marketer can run.
When a campaign is queued and something looks wrong, slow or tiered support costs you real revenue. Mailsoftly answers with real people, and migration help is included rather than sold as a premium tier. That single difference is why most switchers tell us the move felt low risk.

You can bring almost everything that matters: your contact lists, your segments, your templates, and the logic behind your automations. The only things that do not transfer one to one are platform-specific settings and historical send analytics, which stay in Mailjet for your records.
The migration runs in four steps: export from Mailjet, import into Mailsoftly, verify deliverability, then rebuild automations. You can do every step yourself, or hand the whole project to our team, who run a free hands-on migration that gets you live without downtime.
In Mailjet, open Contacts, choose the list you want, and export it to CSV. Include every custom field and the subscription status column so opt-in records travel with each contact. If you keep multiple lists, export them separately and label each file clearly. This single CSV step is the backbone of a clean Mailjet export of contacts, so take a moment to confirm the file opens correctly before moving on.
In Mailsoftly, open Contacts, choose Import, and upload your CSV. Map each Mailjet column to the matching Mailsoftly field, including custom fields, then confirm. Mailsoftly automatically skips duplicates and flags unsubscribed contacts so you never email someone who opted out. For large or multi-list accounts, our team will run the import for you and double-check the field mapping.
Before your first send, authenticate your sending domain with SPF and DKIM records so mailbox providers trust your mail. Then send a seed test to a few inboxes and confirm rendering and placement. It helps to test how your emails render and land across major clients so a template that looked fine in Mailjet still looks right in Mailsoftly. If you are moving a large list, warm up gradually rather than blasting everyone on day one.
Recreate your core flows in Mailsoftly: welcome series, abandoned actions, and re-engagement. Map each Mailjet trigger to its Mailsoftly equivalent, attach the right segment, and run a test contact through the whole journey before you switch it live. Keep the Mailjet version paused but intact for a week as a safety net.
The short version: Mailjet is strong for developer-led transactional email and API workflows, while Mailsoftly is built for marketers who want predictable pricing and human support. The table below sums up the difference (Mailsoftly pricing as of 2026-04-15).
| Platform | Starting price | Free plan | Support | Best for |
|---|---|---|---|---|
| Mailsoftly | $39/mo (Basic, annual) | Yes: 500 contacts, 2,000 emails/mo | Human support plus free migration | Marketers wanting simple, predictable pricing |
| Mailjet | Volume-based tiers (see pricing page) | Yes: limited daily sends | Tiered, paid priority support | Developer-led transactional and API use |
Mailsoftly plans scale in clear steps: Free for 500 contacts and 2,000 emails per month, Basic at $39/mo annual for 5,000 contacts and 40,000 emails, Business at $79/mo annual for 15,000 contacts and 150,000 emails, and Premium at $159/mo annual for 30,000 contacts and 300,000 emails. Enterprise is custom for unlimited contacts and emails. You can see the full breakdown on Mailsoftly’s transparent pricing page, where every tier lists exactly what it includes with no hidden add-ons.
Mailjet prices by volume across separate marketing and transactional products, and several capabilities sit behind higher tiers or paid extras. That model can work well for engineering teams, but for a marketing team it often means tracking more lines on an invoice than the value you actually use.
In your first week, focus on trust and proof: confirm deliverability, send a small real campaign, and watch the numbers before you scale. The goal is to prove the new setup works with low stakes before you commit your full sending volume to it.
Keep your Mailjet account active but paused for a couple of weeks. That gives you a fallback and a place to pull any historical reports you forgot to export, so there is never a moment where you feel locked out of your own data.

Most teams finish in a few hours. A simple list import and template move can be done in under an hour, while accounts with many segments and complex automations take longer to rebuild and test. With our free hands-on migration, you hand over the export and we do the import, mapping, and setup, so your own time commitment is mostly review and approval.
No. Your contacts, custom fields, and subscription status all transfer through a CSV export and import, and duplicates and unsubscribes are handled automatically. Automations move as logic that we rebuild natively in Mailsoftly, so your welcome and re-engagement flows keep working. Keep your Mailjet account paused for a couple of weeks as a safety net while you verify everything.
No. Migration help is free, including the import, field mapping, domain authentication, and automation rebuild. You can also start on the free Mailsoftly plan, which covers 500 contacts and 2,000 emails per month with no credit card, then upgrade only when your list outgrows it. Paid plans start at $39/mo on the annual Basic tier.
It should not, as long as you authenticate your domain and warm up large lists gradually. Set up SPF and DKIM before your first send, start with your most engaged contacts, and scale volume over a few days. Our team helps configure authentication during migration so your sending reputation carries over cleanly.
