Free emailing tools for nonprofits

Is Mailchimp free for nonprofits, and how does Zeffy compare?

Mailchimp does have a free plan. It stops at 250 contacts and 500 sends a month, with a cap of 250 in any single day, and it has no donation or fundraising forms. Its nonprofit discount applies to the paid Marketing plans you would move to once you outgrow that, so it never reduces the free tier. Paid plans meter on both the contacts you store and the emails you send, and going over either one triggers overage charges.

Zeffy is free at any size: unlimited contacts, and 5,000 emails a day or 30,000 once you've connected your own sending domain. Set that against Mailchimp's free plan and it's every contact you have instead of 250, with a daily allowance ten times their monthly one.

Email is also only one part of it. Zeffy is an all-in-one fundraising platform with a full donor CRM underneath, so the place you write your newsletter is already where your donations, tickets, memberships and donor records live. The person who gave in March is on the list when you write in November, with nothing to sync and nothing to export. If you're moving over, you can connect your Mailchimp account and pull your contacts straight across.

Current figures on Zeffy vs Mailchimp and Zeffy vs Constant Contact, which is also where you'll find that Constant Contact has no free plan at all, only a 30-day trial.

Is Zeffy's email and newsletter tool really free?

Yes, the whole thing. No subscription, no per-contact tier, no charge for how often you send, and no feature held back for a paid plan you'll get nudged toward in six months. Your list can double and your bill stays at nothing.

Zeffy is free to your organization with no conditions attached. Separately, anyone paying through a Zeffy checkout is offered the option to add a voluntary contribution, and they're free to skip it.

Is there a limit on how many contacts or subscribers I can email?

Your contact list is unlimited. There's no paid subscriber tier at any size, so storing 800 contacts and storing 80,000 cost the same, and you're never nudged into deleting people to stay inside a band. That's the opposite of how email tools usually price, where the monthly bill steps up every few hundred contacts whether you email them or not.

One practical thing to plan for. You can email 5,000 people a day, or 30,000 once you've connected your own sending domain. Confirmations, receipts and thank-you emails sit outside that, so a busy campaign day never eats into your newsletter. If your list is bigger than a day's allowance you spread it across two, and you can exclude lists from a send so nobody gets it twice.

Do I have to re-import my Mailchimp or Constant Contact list, or does it sync with my donor data?

Your Zeffy contacts are already there. Anyone who donates, buys a ticket, signs up through a form or joins from a newsletter sign-up form is added automatically, so there's no second list to keep in step with the first. That's the part that usually eats an afternoon each month.

If your list is in Mailchimp you can connect the account and pull your contacts straight across. From anywhere else, Constant Contact included, you export your subscribers and upload them with Zeffy's import template. Files hold up to 15,000 records, so a big list comes over in a few batches, and each batch is tagged with its import date so you can always see exactly what you uploaded and when. If an import goes wrong you can undo it.

Can I email a specific group of donors rather than everyone?

Yes, and this is where sitting on your donor data starts paying off. Filter by what someone has given, when they last gave, whether they're a recurring donor or a member, which campaign brought them in, plus language, location, company or a list you built by hand. Stack as many as you like and choose whether a contact has to match all of them or just one. The one thing you can't filter on yet is a custom contact property, so if you plan to segment on something like a birthday, keep it in a note or a list for now.

Then save the result and send to it. A dynamic list keeps itself current, adding contacts whenever they start matching your filters, so "lapsed donors who gave over $500" is a list you build once rather than rebuild every appeal. A manual list is a fixed snapshot for when you want exactly the people who qualified today. If you're coming from Mailchimp, your tags become lists and filters here: same idea, different vocabulary.

Does Zeffy send donation receipts and confirmations automatically?

Yes, and they're separate from your newsletters. A confirmation goes out immediately after every successful payment, with the tax receipt or e-ticket attached where one was generated, and it happens whether or not you ever send a campaign email. You can edit the thank-you email per form and it picks up your brand colors on its own.

Receipts ignore unsubscribes, which is what you want, because a donor should always get proof of their gift. They also stay out of your email reporting, so if you're checking whether one landed, look at the payment rather than your sent emails.

Does Zeffy support email automation like a welcome series?

More than you'd expect, with one real gap.

What's automated today runs off your campaigns. Every form can send a smart invite, either straight away or scheduled for a date you choose. It can then send a follow-up aimed only at the people who opened the invite and didn't complete, which is the nudge that actually recovers revenue. Events, raffles, auctions and memberships get timed reminders before the date, and a recap afterwards. On top of that, confirmations and receipts fire on every transaction, and your year-end tax receipt reminder goes out on its own.

The gap is a series triggered by someone joining a list, so a three-email welcome sequence for new subscribers isn't there yet. If that's central to how you email today, it's worth knowing before you switch.

Will my newsletters land in inboxes rather than spam?

Two routes, and both are built to land. Send from Zeffy's own sending domain, already configured with SPF, DKIM and DMARC and monitored for reputation, with no DNS work from you. Or connect your organization's own domain so mail arrives from your address rather than a platform one, which builds your own sender reputation over time and raises how many people you can reach in a day. Setup walks you through three DNS records and can configure common providers automatically, though changes can take up to 48 hours to propagate.

Either way you set the sender name so your message arrives from your organization, and bulk emails go out so recipients can't see each other's addresses. Two things are required before your first send regardless of which route you pick: a linked bank account and a verified email address. Both exist to stop free email tools being used for phishing.

If someone buys a ticket or donates, can they opt into my newsletter at the same time?

Not from the checkout itself, but you may not need it to. Everyone who donates or buys a ticket becomes a contact automatically, so you can already email them from your contact list without asking them to sign up twice.

When you want explicit newsletter consent, use a sign-up form. Create one under Contacts, embed it on your website or share the link, and pick the list new subscribers land in so they're grouped and ready to email. You can also add a communication preferences question and send each option to its own list, which is how you separate a monthly newsletter audience from an event-only one.

Worth avoiding: adding your own opt-in checkbox to a donation form. The answer is saved on the contact, but custom question answers can't be filtered or grouped yet, so you'd have no way to build a list from them afterwards.

What happens when someone unsubscribes?

They stop receiving the emails you send and they stay in your contact list. An unsubscribed badge appears on their profile, their address is greyed out, and they're excluded from bulk sends automatically so you never have to remember to deselect them. Their giving history stays intact.

Unsubscribing is account-wide rather than per campaign, so someone who opts out and then buys an event ticket next year still gets their confirmation but none of that event's emails. You can also unsubscribe or re-subscribe someone yourself from their contact page if they ask you directly. Every email you send carries an unsubscribe link and footer automatically, which is both a legal requirement and the thing that protects your deliverability.

Can I see who opened and clicked?

Yes, down to the individual recipient. Each send gives you the date and time, how many people it went to, the campaign it belongs to and overall performance, then a table you can filter person by person. Individuals show as delivered, pending, opened, clicked, purchased, unsubscribed or bounced, and bounces tell you whether the address was invalid, the inbox was full, or the server rejected it. You can also come at it from the other direction: a contact's own profile shows the emails you've sent them and whether they opened them, so you don't have to remember which send someone was in.

Purchased is the one a standalone email tool can't give you. Because the email and the donation form are the same system, you can see who gave after clicking, not just who clicked. That turns "the newsletter did well" into a number you can act on.
