Emailing software: complete guide to choosing the right one

In brief: Choosing emailing software is not just a matter of price or a nice-looking editor. Deliverability, GDPR compliance, automation, quality of support: the selection criteria are numerous and not always obvious. This guide sorts through the solutions on the market in 2026, with a concrete comparison to help you see clearly.

More than 8 billion emails a day in France alone. You might think the channel is running out of steam from sheer saturation. Quite the opposite. In 2024, Litmus published an average ROI of 36 dollars for every 1 dollar invested in email marketing. It has been going on for twenty years, and the finding does not change.

Except that to tap into this potential, sending your campaigns from Outlook or Gmail leads nowhere. You need emailing software. Real emailing software. Not a simple sending tool, but a platform that handles large-scale routing, monitors your deliverability and keeps you compliant with the regulations.

What is emailing software and what is it for?

In concrete terms, emailing software gives you the means to create professional messages, route them to thousands of recipients and track what happens next: opens, clicks, bounces. Nothing to do with your Gmail or Outlook mailbox.

Why? Because the infrastructure is in no way comparable. Try sending 5,000 emails from a Gmail account: you will be blocked within minutes. Consumer mailboxes are simply not built for that. Professional emailing software, on the other hand, relies on dedicated routing servers, authentication protocols (SPF, DKIM, DMARC) and a whole system for managing sender reputation.

Emailing software handles three main categories of messages:

• Marketing emails: newsletters, promotions, product launches. The aim is to build loyalty among an existing audience and generate conversions.
• Transactional emails: order confirmation, password reset, delivery notification. Here, sending is triggered automatically after a user action.
• B2B prospecting emails: a category of its own, and often misunderstood. French legislation allows commercial solicitations to be sent to professionals without prior opt-in, under certain conditions. Be careful, however: not all software allows it in its terms of use. This is a point you absolutely must check before signing.

On the market side, the figures speak for themselves. Fortune Business Insights values the global emailing software market at 1.91 billion dollars in 2026, growing by 10.6% a year. In France, Statista projects 226 million euros of spending. And when Salesforce asks SMEs about their number one acquisition channel, 81% answer emailing (2024). The channel is ageing, but it still pays.

The key features of professional emailing software

Not all emailing software is equal. Some is limited to sending basic newsletters, some integrates complete marketing automation tools. Here are the features to look at closely before making up your mind.

A campaign editor and responsive templates

The basics. You must be able to create visually polished emails without touching a line of code. Good software offers a drag-and-drop editor, with modular blocks: text, image, button, columns. All of it must be responsive by default, because more than half of emails are now read on mobile.

Ready-to-use templates save a considerable amount of time. Favour platforms that offer enough of them, and above all in French. A template designed for an English-speaking market will not necessarily suit the habits of your recipients.

Contact database management and segmentation

Sending the same message to your entire database is the best way to watch your unsubscribe rates climb. Emailing software worthy of the name must let you segment your contacts according to varied criteria: business sector, behaviour (opens, clicks), seniority, scoring.

Managing duplicates and invalid addresses (bounced mail) also matters. If your platform does not process bounces automatically, your sender reputation deteriorates and your emails end up in spam. The mechanism is relentless.

Marketing automation

Automation has become a standard. Welcome scenarios, follow-ups after form abandonment, nurturing sequences: these workflows trigger the sending of messages according to each contact’s behaviour, without manual intervention.

In B2B, automation makes it possible, for example, to score your prospects according to how they react to your campaigns, then pass the hottest ones on to the sales team. The time saving is real, provided the platform offers a sufficiently flexible automation module.

Statistics and reporting

Open rate, click rate, click-to-open rate, unsubscribe rate, bounce rate: these indicators are the minimum. The best platforms add geolocation of opens, click heatmaps, consolidated multi-campaign reports and native integration with Google Analytics via UTM parameters.

For reference, the average open rate in France is around 18% according to DMA France (2024), with a click rate of 5.30%. Useful benchmarks for assessing your own performance.

Deliverability

The crux of the matter. An email that does not reach the inbox is useless. Deliverability depends on several technical factors that your emailing software must handle:

• Dedicated IPs: your sends are not mixed with those of other senders. Your reputation belongs to you.
• SPF, DKIM and DMARC authentication: since February 2024, Google and Yahoo have required these protocols for senders of more than 5,000 emails a day. Without them, your messages are rejected.
• Automatic bounce management: processing invalid addresses (hard bounces) and temporarily unavailable ones (soft bounces) protects the quality of your database.
• Reputation monitoring: watching blacklists, feedback loops with ISPs, alerts when the complaint threshold is exceeded (recommendation: below 0.1%).

Integrations

Emailing software never works in isolation. It must connect to your CRM (Salesforce, HubSpot, Pipedrive), your business tools and your existing databases. Two options: native connectors such as Zapier, or an open API for custom integrations.

Incidentally, API quality is an often underestimated criterion. In B2B, two-way synchronisation of contacts between your CRM and your emailing platform avoids double entry and guarantees your segments are always up to date.

How to choose your emailing software: the criteria that count

Typing “best emailing software” into Google returns dozens of comparisons, often sponsored, rarely objective. To see clearly, it is better to start again from your real needs. Here are the selection criteria that make the difference day to day.

Deliverability and technical infrastructure

The first criterion, and yet the one many companies discover too late. Emailing software that does not master its deliverability will cost you time and money.

Since February 2024, Google and Yahoo have tightened their requirements: mandatory SPF, DKIM and DMARC authentication, one-click unsubscribe link (List-Unsubscribe), complaint rate kept below 0.3%. Some companies that were not compliant saw their inbox placement rate fall from 98% to less than 40% overnight.

The question of IPs is just as structuring. With a shared IP, you share your sender reputation with other users of the platform. If one of them has questionable practices, you are the one who suffers the consequences. Dedicated IPs, included with some platforms and billed as an extra with others, give you total control over your reputation.

GDPR compliance and data hosting

In Europe, the GDPR imposes strict obligations on the processing of personal data. The choice of emailing software has a direct impact: where is your contacts’ data hosted? With which processor? In which country?

American platforms (Mailchimp, ActiveCampaign) generally host data in the United States. Despite the Data Privacy Framework, transatlantic transfers remain a point of vigilance for companies subject to strong compliance requirements.

French solutions offer a clear advantage on this point: hosting in France, GDPR-compliant processing contracts, knowledge of the specific requirements of the CNIL, the French data protection authority. For companies that process sensitive data or work with the public sector, this criterion becomes a deal-breaker.

Support and guidance

When a send of 50,000 emails is scheduled for tomorrow morning and a technical problem arises, the quality of support makes all the difference. A chatbot in English is not enough.

The best French emailing software includes telephone support in the subscription, with contacts who understand the particularities of the French market: CNIL regulations, B2B habits, postcodes, data formats. This is not a minor detail.

Beyond technical support, some platforms offer strategic guidance: deliverability audit, advice on segmentation, campaign optimisation. This type of service has real value, especially when you are starting out or changing solution.

Pricing model

The pricing grids of emailing software are rarely directly comparable. Some charge by number of contacts, others by volume of emails sent. Some offer prepaid credits, others only monthly subscriptions.

The most frequent traps:

• The attractive free tier: free up to 300 emails a day, but the advanced features (automation, dedicated IPs, API) are locked behind expensive paid tiers.
• The cost per contact: advantageous if your database is small, penalising when it grows. Going from 1,000 to 10,000 contacts can multiply the bill by five.
• Credits that expire: you buy a sending volume, but if you do not use it within the month, it is lost. For companies that send irregularly, trade shows, launches, seasonality, it is a wasted item of expenditure.

The right model depends on your sending rhythm. For regular campaigns, the monthly subscription is often more economical. For one-off or seasonal sends, credits with no expiry date represent a real advantage.

B2B prospecting: a specific need

In B2B, email prospecting does not work like B2C marketing. The CNIL allows commercial messages to be sent to professionals without opt-in, as long as the content relates to their job and an unsubscribe link appears in the email. So far, nothing complicated.

Where it gets tricky is that Mailchimp requires proof of consent for every imported contact. ActiveCampaign, the same. The majority of mainstream emailing software simply prohibits cold prospecting in its terms of use.

If your business relies on B2B prospecting, check this point from the outset. Choosing software that allows and optimises this use (CAPTCHA handling, intelligent bounce retries, dedicated IPs for prospecting) will spare you having to migrate after six months.

Comparison of emailing software in 2026

Rather than listing twenty tools without ranking them, let us concentrate on the six platforms most representative of the market. Each meets a different usage profile.

What this comparison reveals

Brevo (formerly Sendinblue) dominates in name recognition thanks to its free offer and its all-in-one positioning (email, SMS, CRM, chat). A good entry point for very small businesses that are starting out. But the advanced features, telephone support and dedicated IPs are only accessible on the higher tiers, which are considerably more expensive.

Sarbacane positions itself in the premium segment with strong human guidance: dedicated coach, predictive AI, complete suite. The price reflects this positioning. The platform suits SMEs that want to be guided and that mainly send to opt-in databases.

Mailjet appeals to technical profiles and developers thanks to its robust API and its SMTP/transactional orientation. Less suited to B2B prospecting or the creation of sophisticated visual campaigns.

Mailchimp remains the best-known name, carried by years of intensive marketing and a generous free offer. But its limits quickly appear for the French market: data hosted in the USA, support in English only, B2B prospecting strictly prohibited, dedicated IPs reserved for very large volumes.

ActiveCampaign excels at advanced marketing automation. The possible scenarios are among the most complete on the market. On the other hand, data hosted in the United States, no support in French, B2B prospecting not allowed. And the price rises quickly with the number of contacts.

Ediware occupies a specific position: B2B specialist, dedicated infrastructure included (IPs, PowerMTA), French hosting, expert support in French and prospecting allowed. The model of credits without expiry brings a concrete advantage for companies that do not send every month.

Why choose French emailing software like Ediware

Since 2002, Ediware has supported more than 4,000 companies in their B2B email marketing campaigns. Not a start-up that pivots every six months. An email marketing platform built on more than twenty years of field experience, designed for the realities of the French market.

An infrastructure built for deliverability

At Ediware, every customer has dedicated IPs from the Pro plan upwards. Not a paid option: a standard. The platform relies on PowerMTA technology, the same sending engine used by the largest professional routers. SPF, DKIM and DMARC authentication is configured automatically, and blacklist monitoring runs continuously.

In practice, this means your sender reputation depends only on your own practices. No nasty surprises linked to another user sharing your IP.

Hosting in France and native GDPR compliance

All data is hosted in France. Not in Ireland, not in the Netherlands, not in the United States. In France. For companies subject to strict compliance obligations, or those working with local authorities and public bodies, the argument is decisive.

The GDPR is not a patch added afterwards to an American platform. It is built into the architecture of the solution: consent management, right to object, traceability of processing.

B2B prospecting, a fully authorised use

This is probably the point that most sets Ediware apart from mainstream solutions. B2B commercial prospecting by email is a legitimate use, regulated by the CNIL. Ediware explicitly allows it and has developed tools to optimise it: automatic handling of CAPTCHAs encountered on web forms, intelligent retries of soft-bounced addresses, automated processing of invalid addresses.

Platforms such as Mailchimp or ActiveCampaign prohibit this use in their terms and conditions. Which forces B2B companies to get around the rules or juggle several tools.

Support that speaks your language

Telephone support in French is included in all plans. Ediware advisers have on average more than ten years of experience in email marketing. Not level-1 operators reading a script. Experts who know the issues of deliverability, the specific requirements of the CNIL, best practices in B2B segmentation.

The platform also offers training, webinars and strategic guidance for companies wishing to build their emailing skills.

A business model designed for B2B

In B2B, sends are not always regular. A prospecting campaign before a trade show, a quarterly follow-up, a one-off product launch. The model of credits with no expiry date offered by Ediware answers this reality. You buy a volume, you use it at your own pace.

For companies that send regularly, subscription plans start at €98 a month for 50,000 emails, with dedicated IPs and AI assistant included. The Premium plan at €198 a month adds automation, unlimited landing pages and API access.

FAQ: frequently asked questions about emailing software

What is the best free emailing software?

Several platforms offer a free plan: Brevo (300 emails/day), Mailjet (6,000 emails/month), Mailchimp (500 emails/day). These free versions are useful for testing, but they have serious limitations: no dedicated IPs, no automation, restricted support. For regular professional use, migrating to a paid plan quickly becomes unavoidable.

What is the difference between emailing software and a marketing automation tool?

Emailing software lets you create and send email campaigns. A marketing automation tool goes further: it automates complete sequences according to contact behaviour, such as welcome scenarios, scoring or conditional follow-ups. Today, most professional emailing software integrates automation features. The boundary between the two is blurring.

Is French emailing software better suited to the GDPR?

In practice, yes. French platforms host data in France or in the EU, which simplifies compliance. They natively integrate consent management, the right to object and traceability of processing. And above all, they know the specific requirements of the CNIL, in particular the distinction between B2C opt-in and B2B opt-out.

How much does professional emailing software cost?

Prices vary according to sending volume and features. Expect between 50 and 200 euros a month for the standard plans of the main platforms. Watch out for hidden costs: dedicated IPs as an extra, telephone support billed separately, automation features locked on the higher tiers. The right reflex is to compare the total cost over 12 months, not just the advertised entry price.

Can you do B2B prospecting with emailing software?

It depends on the platform. In France, the CNIL allows commercial emails to be sent to professionals without prior consent, provided the message relates to their job and an unsubscribe link is present. But Mailchimp and ActiveCampaign prohibit cold prospecting in their terms of use. Platforms such as Ediware allow it and offer dedicated tools to optimise this use.

How can you improve deliverability with emailing software?

Three main levers: use dedicated IPs to control your sender reputation, configure SPF/DKIM/DMARC authentication correctly, and clean your contact database regularly by removing invalid addresses. The complaint rate must stay below 0.1%. Your emailing software must monitor these indicators and alert you if they deteriorate.

Do you need dedicated or shared IPs?

If you send more than 5,000 emails per campaign, dedicated IPs are strongly recommended. They give you total control over your reputation. With shared IPs, your results also depend on the practices of the other users sharing the same IP address. For B2B prospecting in particular, dedicated IPs are practically indispensable.
